Assignment Demo

Welcome to the Assignment Demo. In this assignment, we’ll be exploring functions in R and their applications. Please follow the instructions closely and ensure you understand each function’s utility.

Stats Team

Objective

For each function assigned to you, perform the following tasks:

  1. Data Frame Creation:
    • Create a data frame related to a topic of your interest. It should have at least 7 rows.
    # Example using Disney Movies
  disney_movies <- data.frame(
  Movie = c("The Lion King", "Frozen", "Aladdin", "Mulan", "Beauty and the Beast", "Tangled", "Pocahontas"),
  Release_Year = c(1994, 2013, 1992, 1998, 1991, 2010, 1995),
  IMDb_Rating = c(8.5, 7.4, 8.0, 7.6, 8.0, 7.7, 6.7),
  Protagonist = c("Simba", "Elsa & Anna", "Aladdin", "Mulan", "Belle", "Rapunzel", "Pocahontas"),
  Antagonist = c("Scar", "Duke of Weselton", "Jafar", "Shan Yu", "Gaston", "Mother Gothel", "Governor Ratcliffe"),
  Main_Song = c("Circle of Life", "Let It Go", "A Whole New World", "Reflection", "Beauty and the Beast", "I See the Light", "Colors of the Wind")
)
# Display the created data frame

  2. Function Application:
    • Apply your assigned function to the data frame.
    # Example for the head() function
head(disney_movies)
    ##                  Movie Release_Year IMDb_Rating Protagonist       Antagonist
## 1        The Lion King         1994         8.5       Simba             Scar
## 2               Frozen         2013         7.4 Elsa & Anna Duke of Weselton
## 3              Aladdin         1992         8.0     Aladdin            Jafar
## 4                Mulan         1998         7.6       Mulan          Shan Yu

## 6              Tangled         2010         7.7    Rapunzel    Mother Gothel
##              Main_Song
## 1       Circle of Life
## 2            Let It Go
## 3    A Whole New World
## 4           Reflection
## 5 Beauty and the Beast
## 6      I See the Light
    head(disney_movies, 2)
    ##           Movie Release_Year IMDb_Rating Protagonist       Antagonist
## 1 The Lion King         1994         8.5       Simba             Scar
## 2        Frozen         2013         7.4 Elsa & Anna Duke of Weselton
##        Main_Song
## 1 Circle of Life
## 2      Let It Go
  3. Function Notes:
    • Describe the input and output of your function.
    Notes: Input: head(data_frame) or head(data_frame, n) Output:
    • By default, head() displays the first 6 rows of a data frame.
    • head(data_frame, n) returns the first n rows of a data frame.

Assigned Functions:

Here are the functions assigned to each team member:

Name Assigned Function
Christina Nguyen head()
Marina Zhao tail()
Gardenia Chang str()
Kelly Zhen summary()
Jack Oberdorfer length()
Emily Zhu dim()
Wesley Martinez class()
Francesca Casimiro names()

Theory Team

Objective

Enhance your R Markdown skills by incorporating various textual and code-related elements.

  1. Text Elements:
    • Title
    • Subtitle (name, date, etc.)
    • Various text formatting: Bold, Italic, Strikethrough, > Blockquote, – Endash
    • Lists and Tables
  2. Code Chunks:
    • Include a string.
    • Define a variable.
    • Display a math equation of your choice.
  3. External Data:
    • In a separate CSV file, create a table (at least 3 columns and 5 rows).
    • Import the CSV into RStudio.
    # Importing example
#your_dataframe <- read.csv("your_file.csv")
  4. Vector and Data Frame Creation:
    • Define 5 vectors that align with the info in your table.
    • Combine these vectors into a data frame. This should resemble your CSV table.
