When you have data in a CSV, you can load it into a data frame in R using readr‘s read_csv() function:

df <- read_csv('my_csv_file.csv')

• In the example above, the read_csv() function is called
• The CSV file my_csv_file.csv is passed in as an argument
• A data frame containing the data from my_csv_file.csv is returned

You can also save data from a data frame to a CSV using readr‘s write_csv() function:

write_csv(df,'new_csv_file.csv')

In the example above, write_csv() takes two arguments:

• df, which represents a data frame object
• new_csv_file.csv, the name of the CSV file that will hold the data from the data frame

By default, this method will save the CSV file to your current directory.
