Functions

Functions are a way to compartmentalize chuncks of code so you can use them over and over.

For this homework, I would like you to create a function called get_rice() and it will do the following:

• Load in the csv file from google docs.
  
• Make columns for Date, Month, & Weekday.
  
• Convert Temperature & Length units to metric version.
  
• Drop all duplicate data.
  
• Make column names readable and usable.
  
• Return the data frame to the user.

I’ll get you started with the URL and the stub for the function. If you want to look at the raw data

# Put your code here for the function.
get_rice <- function() {
  url <- "https://docs.google.com/spreadsheets/d/1Mk1YGH9LqjF7drJE-td1G_JkdADOU0eMlrP01WFBT8s/pub?gid=0&single=true&output=csv"

}

When done, you should be able to call the function as:

rice <- get_rice() 
summary( rice )

   Length     Class      Mode 
        1 character character 

Put it into a script file.

Copy the code for the function above and put it into a *.R script file and save it in the root directory of your project for this class. Now you can use it whenever we need to load in that particular data file.
