R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

z<-c(723,15,1234,-10,99983)
z[3:3]

## [1] 1234

z[3:4]

## [1] 1234  -10

z[c(3,4,5)]

## [1]  1234   -10 99983

x<-4.5678
class(x)

## [1] "numeric"

x<-as.integer(x)
x<-6.87
x<-as.numeric(x)
x<-as.character(x)
class(x)

## [1] "character"

#Create a vector

##Numeric vector
x<-5.6 
class(x)

## [1] "numeric"

y<-c(3,4,6,7,8)
y

## [1] 3 4 6 7 8

class(y)

## [1] "numeric"

z<-c(3.4, 7.8, 6.7, 7, 9)
z

## [1] 3.4 7.8 6.7 7.0 9.0

class(z)

## [1] "numeric"

name<-c("Tom","Harry", "Swan")
class(name)

## [1] "character"

name

## [1] "Tom"   "Harry" "Swan"

z[2:4] #consecutive

## [1] 7.8 6.7 7.0

z[c(1,3,5)] #Square brackets are always used for slicing

## [1] 3.4 6.7 9.0

z<-c(2,3,6,9,10,14)
plot(z)

plot(z[2:5])

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
