Chapter 2: More on Vectors and Data Frames Operations

Introduction

R has numerous packages and built-in datasets. They are freely available and are excellent tools to learn and practice data analyses. To use a package, first one should install them using the function install.packages(). We only need to install a package once. After installing and in order to use a package, we need to load the package in the working environment. We use the library() function or require() function to load a package, everytime the RStudio is launched. Inside the parantheses of library() or require() functions, we use "" marks to name the target package we want to load.

Like R itself, packages are versioned and updated. The Check for package Updates, under the tab of Packages in Files, Plots, Packages, Help, and Viewer pane search for new versions of the packages and gives the user a chance to update those packages that are out of date. If using codes instead, the function update.packages() does the job.

The aim of this chapter is to elaborate more on vectors and data frames operations. Using six comprehensive examples developed by the authoer, We focus on the the most important and basic functions to call, create, change and examine the vectors and data frames, which are the pillars of R and data analysis. Particulalry, We learn working with the following fucntions in this document: install.packages(), library(), require(), update.packages(), summary(), length(), str(), mean(), max(), min(), names(), which(), seq(), order(), sort(), c(), rep(), match(), %in%, is.na(), !is.na(), gl(), levels(), factor(), read.table(), getwd(), setwd(), sample()

Example 1: Calling a Package and Inspecting a Dataset in It

Install the package UsingR. Load the package into R environment. This package has a dataset called exec.pay, which is a vector data. Examine the dataset. Particularly:

a) Examine this dataset, its summary and length.
b) Calculate its mean, trimmed mean for 10%, and then 25%.

Example 1 Solutions

a) Because we have already installed and reloaded the package, here I have put codes related to its installation but have set eval and include to FALSE so that no code will be shown or run in the output of RMarkdown file. We can always set such specification by pressing Modify chunk options

The package is installed. So, we can call its contents using the library() function. We have asked RMarkdown to run the code for us but not show the output, by setting include=FALSE

Now, we call the exec.pay dataset.

exec.pay

To examine the contenct of exec.pay, we can use summary(), length(), str()functions. Notice that we do not need "" to put around the dataset name, when using summary(), length(), str(). Putting "" around the name of a dataset in arguments of those functions causes the whole term to be treated as a character variable, and not as a dataset anymore.

The function str() gives us some understanding about the structure of the dataset.For example, its elements and wether it is a vector or matrix, etc.

summary(exec.pay)

##    Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
##    0.00   14.00   27.00   59.89   41.50 2510.00

length(exec.pay)  #returns the length of the vector.

## [1] 199

str(exec.pay)

##  num [1:199] 136 74 8 38 46 43 9 9 12 11 ...

Now we examin the mean of this vector and its two trimmed versions:

mean(exec.pay)

## [1] 59.88945

mean(exec.pay, trim = 0.1)    # 10% of data are trimmed from beginning and the end (a total of 20% of data is gone).

## [1] 29.96894

mean(exec.pay, trim = .25)    # mean after 25% trimed data.

## [1] 26.66337

Example 2: Calling, Subsetting, Sorting and Combining

The rivers data set is stored as a vector, including the length (in miles) of USA rivers. This dataset is part of the UsingR package which we have already installed and summoned in the previous example.

a) Examine the dataset and identify its summary. Indicate how many observations are in this dataset.
b) Calculate the min, max, mean and mean of 20% trimmed version of data.
c) Examine whether there are rivers longer than 500 miles. If So, return their values.
d) Identify the position of elements bigger than 500 in the vector. Hint: use function which().
e) Return the first 10 rivers’ lengths in the dataset rivers. Next, return elements in the following positions 19, 23, 87 and 99.
f) Return elements with the odd index. Hint: use the seq() function, standing for sequence.
g) Print the 10 shortest and 10 longest rivers and save them in seprate vectors. Hint: this can be done using either order() or sort() functions.
h) Make a combined vector that only contains the 10 longests and 10 shortest rivers.

g) Using order() function.

position_of_rivers_in_ascending_order = order(rivers) #retturns the position of each element, had they been ascendingly ordered. 

rivers_ordered =rivers[position_of_rivers_in_ascending_order] #returns an ascendingly ordered version of data.

Now, we do the same using sort() function, returns the sorted version of a vector. So, in that, it differs from order() which only returns the position of each element, had they been sorted. sort() does the job completely and returns the sorted version of a vector. The argument decreasing= determines whether we would like our data to be sorted ascending or descending.

rivers_sorted = sort(rivers, decreasing = FALSE) 

rivers_sorted [1:10]   # ten shortest rivers.

ten_shortest = rivers_sorted[1:10]
ten_longest = rivers_sorted[c(a:l)]

Top_short_and_long_rivers = c(ten_longest,ten_shortest)
Top_short_and_long_rivers

Example 3: Creating, Naming, Subseeting, and Modifying

Imagine you have recorded number of steps (in thousands) you took during the day for a period of two weeks. These numbers are in order of days (starting from Saturday) and as following:

2,6, 12, 22, 1.7, 7.9, 10.2, 12.5, 4,6,5.8, 9.9, 21.9, 7.9

a) Make a vector of walks you took, and name the days, starting from Saturday. Hint: use the rep() function.
b) Identify in which days you have walked more than 10 thousands steps. Make a percentage.
c) Check if 22 is among the number of this vector and in what position in the vector.
d) Oops, in the vector, the values 7.9 are wrongly entered. Replace all 7.9 values with 8.3.

c) match(a, my_object) checks whether a exists in my_object which could be a vector, table, etc. and returns the first position that the match happens.

%in% is a more intuitive way checking whether the element on the left side of it exists in the right element. The outcomes is a logical value, TRUE or FALSE.

Note: The difference between which() and match() is that the input for which is a condition or a boolean variable. However, the input to match is simply a number or a vector to be checked with a reference vector or variable.

Example 4: Working with Missing Data

Below are students’ grades in a class of 15 people (grades are beween 0 to 20). There are missing data in this dataset.

Grades: 10, 9, 18, 19, 20, NA, 11, 14.5, 16, 17.5, 20, NA, 13, 13.8, NA

a) Create a vector of grades and examine its properties
b) Does value 17 exist in grades of this class?
c) What is the average of the class grades? How should one get rid of NAs to calculate the mean? Create a new vector of grades by removing all the missing data and calcualte the average.
d) It turns out that the first missing data is actually 14. Replace it.
f) Return all elements that are smaller than or equal to 16 and bigger than 10.

Example 4 Solutions

grades=c(10, 9, 18, 19, 20, NA, 11, 14.5, 16, 17.5, 20, NA, 13, 13.8, NA)

summary(grades)  # when mean is being calculated, NAs are autoamtically ignored and not counted in the total number of observations either.

##    Min. 1st Qu.  Median    Mean 3rd Qu.    Max.    NA's 
##    9.00   12.50   15.25   15.15   18.25   20.00       3

str(grades)

##  num [1:15] 10 9 18 19 20 NA 11 14.5 16 17.5 ...

length(grades)  #NAs are counted.

## [1] 15

grades == 17

##  [1] FALSE FALSE FALSE FALSE FALSE    NA FALSE FALSE FALSE FALSE FALSE
## [12]    NA FALSE FALSE    NA

mean(grades) # this returns NA as a result, simple because the vector contains NA values.

## [1] NA

So, we need to take care of missing values first. If you try the following code, you see that R does not return what we want. The R itself suggests to use is.na() function.

which(grades==NA)  # does not work. For NAs, use is.na().

## integer(0)

Note: is.na() checks for all the elements in a vector and see whether they are NA. If so, it returns TRUE for that element.

is.na(grades)

##  [1] FALSE FALSE FALSE FALSE FALSE  TRUE FALSE FALSE FALSE FALSE FALSE
## [12]  TRUE FALSE FALSE  TRUE

The outcome of this function is a vector of logical values. We use it in our favor smartly.

grades[!is.na(grades)]  # returns those elements whose values are NOT NA.

##  [1] 10.0  9.0 18.0 19.0 20.0 11.0 14.5 16.0 17.5 20.0 13.0 13.8

Note: is.na() returns the boolean value TRUE or FALSE by checking each element in vector to see whether they are NA (i.e., missing). If they are NA, it returns TRUE. The outcomes thus is a vector of true and false values. If we use that outcome for returning values, such as in grades[is.na(grades)], then elements whose values are NA are returned (because they had the TRUE value). What we want is the opposite of that. That is, elements that are NOT NA. So we use the logical symbol ! which is logical negation or NOT.

new_grades_list = grades[!is.na(grades)]
mean(new_grades_list)  # now the mean() function works.

## [1] 15.15

which(is.na(grades)==TRUE) # runs the logical operation and returns the place of missing data.

## [1]  6 12 15

grades[6] = 14  # now we replace the 6th element, where the 1st missing data was. 
grades

##  [1] 10.0  9.0 18.0 19.0 20.0 14.0 11.0 14.5 16.0 17.5 20.0   NA 13.0 13.8
## [15]   NA

grades[grades>10 & grades<=16]  # also includes the NAs.

## [1] 14.0 11.0 14.5 16.0   NA 13.0 13.8   NA

Example 5: Working with Factors and Their Levels

Factors are vectors of categorical data. Imagine a column in your dataset that indicates what conditions your participants belong to. So factors are essentially vectors with a total length equal to our number of observations. However, factors have levels equal to a number of experimental groups we had.

a) Make a factor with 21 observations that belong to three levels/groups of Powerful, Control and Powerless, each with 7 observations. Hint: Use functions rep() or gl().
b) Add two additional levles to your factor namely, Dominance and Prestigue.
c) Recode the levels into shorter terms as (PF, PL, C, Do, and Pres)
d) Drop the observations of the control group.
e) Replace level lables of the factor with numbers from (1 to 4) instead of characters.

Example 5 Solutions

# Method 1. Using rep() function. 

observations_vec = rep(c("powerful", "control", "powerless"), times=7)
observations_vec  # so far this is vector. We should turn it into a factor.

##  [1] "powerful"  "control"   "powerless" "powerful"  "control"  
##  [6] "powerless" "powerful"  "control"   "powerless" "powerful" 
## [11] "control"   "powerless" "powerful"  "control"   "powerless"
## [16] "powerful"  "control"   "powerless" "powerful"  "control"  
## [21] "powerless"

observation_factor = factor(observations_vec)
observation_factor

##  [1] powerful  control   powerless powerful  control   powerless powerful 
##  [8] control   powerless powerful  control   powerless powerful  control  
## [15] powerless powerful  control   powerless powerful  control   powerless
## Levels: control powerful powerless

The function gl() stands for generate levels, generates levels for factor by specifying pattern of their levels. gl(n, k, length = n*k, labels = vector of labels, ordered = FALSE) is a general format.

# Method 2. Using gl() function. 
power_factor= gl(3,7, labels= c("powerful", "control", "powerless"))
power_factor

##  [1] powerful  powerful  powerful  powerful  powerful  powerful  powerful 
##  [8] control   control   control   control   control   control   control  
## [15] powerless powerless powerless powerless powerless powerless powerless
## Levels: powerful control powerless

Note: Did you see the difference between the outcomes of Method 1 vs. 2 ?

b) Basically the best way is to redefine the factor.

power_factor2= gl(5,7, labels= c("powerful", "control", "powerless", "dominance", "prestige"))
power_factor2

##  [1] powerful  powerful  powerful  powerful  powerful  powerful  powerful 
##  [8] control   control   control   control   control   control   control  
## [15] powerless powerless powerless powerless powerless powerless powerless
## [22] dominance dominance dominance dominance dominance dominance dominance
## [29] prestige  prestige  prestige  prestige  prestige  prestige  prestige 
## Levels: powerful control powerless dominance prestige

levels(power_factor2) # returns the levels of the factor.

## [1] "powerful"  "control"   "powerless" "dominance" "prestige"

levels(power_factor2) = c("PF", "C", "PL", "Do", "Pres") # here we assign new labels. 
power_factor2

##  [1] PF   PF   PF   PF   PF   PF   PF   C    C    C    C    C    C    C   
## [15] PL   PL   PL   PL   PL   PL   PL   Do   Do   Do   Do   Do   Do   Do  
## [29] Pres Pres Pres Pres Pres Pres Pres
## Levels: PF C PL Do Pres

d) Remember that our factor is essentially a vector. So we can find specific elements in it and return them.

which(power_factor2!="C") #returns where in the factor/vector we do NOT have a control group.

##  [1]  1  2  3  4  5  6  7 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
## [24] 31 32 33 34 35

positions= which(power_factor2!="C")
power_factor2[positions]  # if needed, we can make a new factor out of this too, as below.

##  [1] PF   PF   PF   PF   PF   PF   PF   PL   PL   PL   PL   PL   PL   PL  
## [15] Do   Do   Do   Do   Do   Do   Do   Pres Pres Pres Pres Pres Pres Pres
## Levels: PF C PL Do Pres

reduced_power_vec = power_factor2[positions] 
reduced_power_factor = factor(reduced_power_vec)
reduced_power_factor

##  [1] PF   PF   PF   PF   PF   PF   PF   PL   PL   PL   PL   PL   PL   PL  
## [15] Do   Do   Do   Do   Do   Do   Do   Pres Pres Pres Pres Pres Pres Pres
## Levels: PF PL Do Pres

levels(reduced_power_factor) = c(1,2,3,4)
reduced_power_factor

##  [1] 1 1 1 1 1 1 1 2 2 2 2 2 2 2 3 3 3 3 3 3 3 4 4 4 4 4 4 4
## Levels: 1 2 3 4

Example 6: Dropping Factor Levels

In the process of cleaning datasets, you may end up removing all the data corresponding to a factor level. Consider this dataset of times to travel into work using different modes of transport:

 getting_to_work = data.frame( mode = c("bike", "car", "bus", "car", "walk", "bike", "car", "bike", "car", "car"),  time_mins = c(25, 13, NA, 22, 65, 28, 15, 24, NA, 14) ) 

 getting_to_work

##    mode time_mins
## 1  bike        25
## 2   car        13
## 3   bus        NA
## 4   car        22
## 5  walk        65
## 6  bike        28
## 7   car        15
## 8  bike        24
## 9   car        NA
## 10  car        14

Imagine that we would like to only have cases whose values under time_mins are not missing. We can do this using the subset() function:

a = subset(getting_to_work, !is.na(time_mins))
a

##    mode time_mins
## 1  bike        25
## 2   car        13
## 4   car        22
## 5  walk        65
## 6  bike        28
## 7   car        15
## 8  bike        24
## 10  car        14

Note: Looking at the mode column, there are now just three different values in the subset dataframe, but we still have the same four levels in the factor. We can see this with the levels()function:

levels(a$mode)

## [1] "bike" "bus"  "car"  "walk"

If we want to drop the unused levels of the factor, we can use the droplevels() function. This accepts either a factor or a data frame. In the latter case, it drops the unused levels in all the factors of the input. Since there is only one factor in our example data frame, the two lines of code in the next example are equivalent:

a$mode = droplevels(a$mode) 
a = droplevels(a) 
levels(a$mode)

## [1] "bike" "car"  "walk"

Example 7: Practicing with Ordered Factors

Some factors have levels that are semantically greater than or less than other levels. This is common with multiple-choice survey questions. For example, the survey question “How happy are you?” could have the possible responses depressed, grumpy, so-so, cheery, and ecstatic. The resulting variable is categorical, so we can create a factor with the five choices as levels. Here we generate ten thousand random responses using the sample() function:

responses= sample(c("depressed", "grumpy", "so-so", "cheery", "ecstatic"), 10000, replace = TRUE)

resp_factor = factor(responses)  # this is still an unordered factor. simply nominal.

levels(resp_factor)

## [1] "cheery"    "depressed" "ecstatic"  "grumpy"    "so-so"

str(resp_factor)

##  Factor w/ 5 levels "cheery","depressed",..: 2 3 3 1 1 4 1 4 4 5 ...

summary(resp_factor)  #summarize the frequencies of each category as well.

##    cheery depressed  ecstatic    grumpy     so-so 
##      2055      1951      2009      1994      1991

Now lets turn this factor into an ordered and more meaningful factor.

ordered_resp_factor = factor(responses, levels = c("depressed", "grumpy", "so-so", "cheery", "ecstatic"), ordered = TRUE )

ordered_resp_factor

##     [1] depressed ecstatic  ecstatic  cheery    cheery    grumpy   
##     [7] cheery    grumpy    grumpy    so-so     grumpy    cheery

Example 8: Converting Continuous Variables into Categorical

Imagine we have a sample of 10000 people’s age from 16 to 66 years old. We would like to classify these observations in bins of 10-year-wide.

age = sample(c(16:66), 10000, replace = TRUE)

class(age)

## [1] "integer"

hist(age)  # as this histogram dmeonstrates sample() function has worked quite unifromly.

Now that we have the age vector, we can classify observations on bins with width of our choice. One function to do so is cut(). This function returns a factor vector of classified elements and factor levels are the bins. It is important to understand how cut() works. This function classify elements of its first argument, according to the bins it receives in its second argument. If we have a nicely ordered set of bins, we can apply seq() function to define them, as in example below. However, if the width of these bins are different from each other and they are irregular, then we can simply put the beginnings of each bin in a vector (see the second chunk below)

b = cut(age, seq(16,66, 10))  #Note that the outcome of cut() is a factor.
class(b)

## [1] "factor"

summary(b) # gives us a nice summary of levels and the amount of observations in each bin.

## (16,26] (26,36] (36,46] (46,56] (56,66]    NA's 
##    2038    1934    1952    1917    1947     212

This is an example of dividing numbers from 1 to 100 into bins with unequal width. Notice that the bins do not include the lower limit but include the upper limit bondary. In the following example the bins are (1,5], (5,20], (20,50], (50,90], and (90,100].

a= cut(c(1:100), c(1,5,20,50, 90, 100))  
class(a)

## [1] "factor"

summary(cut(c(1:100), c(1,5,20,50, 90, 100)))

##    (1,5]   (5,20]  (20,50]  (50,90] (90,100]     NA's 
##        4       15       30       40       10        1

Notice that in the above example number 1 has not been included in any category and thus is identified as NA, or missing in the outcome of the cut()wehen we check its summery. Importantly, to solve this issue, one can redefine the first bins such that it includes any number bigger than 0 and smaller or equal to 5. See below:

cut(c(1:100), c(0,5,20,50, 90, 100))

##   [1] (0,5]    (0,5]    (0,5]    (0,5]    (0,5]    (5,20]   (5,20]  
##   [8] (5,20]   (5,20]   (5,20]   (5,20]   (5,20]   (5,20]   (5,20]

##  [36] (20,50]  (20,50]  (20,50]  (20,50]  (20,50]  (20,50]  (20,50] 
##  [43] (20,50]  (20,50]  (20,50]  (20,50]  (20,50]  (20,50]  (20,50] 
##  [50] (20,50]  (50,90]  (50,90]  (50,90]  (50,90]  (50,90]  (50,90]

##  [64] (50,90]  (50,90]  (50,90]  (50,90]  (50,90]  (50,90]  (50,90]

##  [92] (90,100] (90,100] (90,100] (90,100] (90,100] (90,100] (90,100]
##  [99] (90,100] (90,100]
## Levels: (0,5] (5,20] (20,50] (50,90] (90,100]

summary(cut(c(1:100), c(0,5,20,50, 90, 100)))

##    (0,5]   (5,20]  (20,50]  (50,90] (90,100] 
##        5       15       30       40       10

The cut() function also receives lables in its argument. That is becuase in principle, this function is generating a factor, and thus the names of its levels can be fed in via a lable argument.

cut(c(1:100), c(0,5,20,50, 90, 100), labels = c("class1", "class2", "class3", "class4", "class5"))

##   [1] class1 class1 class1 class1 class1 class2 class2 class2 class2 class2
##  [11] class2 class2 class2 class2 class2 class2 class2 class2 class2 class2
##  [21] class3 class3 class3 class3 class3 class3 class3 class3 class3 class3
##  [31] class3 class3 class3 class3 class3 class3 class3 class3 class3 class3
##  [41] class3 class3 class3 class3 class3 class3 class3 class3 class3 class3
##  [51] class4 class4 class4 class4 class4 class4 class4 class4 class4 class4

##  [71] class4 class4 class4 class4 class4 class4 class4 class4 class4 class4

##  [91] class5 class5 class5 class5 class5 class5 class5 class5 class5 class5
## Levels: class1 class2 class3 class4 class5

summary(cut(c(1:100), c(0,5,20,50, 90, 100), labels = c("class1", "class2", "class3", "class4", "class5")))

Example 9: Reading a Table from an External File

the text file Runner, located in the same folder as this file, has three variables in it. We can read the content of a file (e.g., a txtor excel, etc.) using the read.table() function. The function receives the address of file as input and the its outcome is a data frame, and in general is an object. The argument header=TRUE indicates that the first row of the file contains the headers of data.

Note: When reading a file, use the \\ (double backward slash) to indicate the address.

read.table("C:\\Users\\change my name\\Dropbox\\My Teaching & Learning Lectures\\Statistics\\Learning Stat with R\\Learning Stat with R\\2- More on Vector and Data Frame Operations\\Runner.txt", header= TRUE)

##   ID Time weigh
## 1  1   23    80
## 2  2   44    91
## 3  3   52    49
## 4  4   12    65
## 5  5   99    73

we can assign the final table into an object, as follwing:

M = read.table("C:\\Users\\change my name\\Dropbox\\My Teaching & Learning Lectures\\Statistics\\Learning Stat with R\\Learning Stat with R\\2- More on Vector and Data Frame Operations\\Runner.txt", header= TRUE)

M

##   ID Time weigh
## 1  1   23    80
## 2  2   44    91
## 3  3   52    49
## 4  4   12    65
## 5  5   99    73

Now, we read and return contents of the column Time:

M$Time[]

## [1] 23 44 52 12 99

#OR

M[,2]  # everything in second column is returned.

## [1] 23 44 52 12 99

#OR

M[,"Time"]

## [1] 23 44 52 12 99

summary(M$Time[])  # OR summary(M$Time) without brackets.

##    Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
##      12      23      44      46      52      99

Note: R has a working directory, which is the default place that files will be read from or written to. You can see its location with getwd() and change it with setwd():

## [1] getwd() ## [1] “c:/windows”

getwd()

## [1] "C:/Users/change my name/Dropbox/My Teaching & Learning Lectures/Statistics/Learning Stat with R/Learning Stat with R/2- More on Vector and Data Frame Operations"

setwd("C:\\Users\\change my name\\Dropbox\\My Teaching & Learning Lectures\\Statistics\\Learning Stat with R\\Learning Stat with R\\2- More on Vector and Data Frame Operations")
