The “rename” Function in R

• Package: dplyr

• Purpose: To rename columns in a data frame.

• General Class: Data Manipulation

• Required Argument(s):

• data: A data frame.

• ...: A set of column name pairs to rename, where the names on the right-hand side are the current names, and the names on the left-hand side are the new names.

• Notable Optional Arguments:

• None

• Example:

• # Example usage
  library(dplyr)
  
  # Create a sample data frame
  df <- data.frame(A = 1:3, B = c("foo", "bar", "baz"))
  
  # Rename columns in the data frame
  df_renamed <- df %>% rename(new_A = A, new_B = B)
  
  # Print the original and renamed data frames
  print(df)
  print(df_renamed)

• In this example, the rename function from the dplyr package is used to rename columns in a data frame (df). The resulting data frame with renamed columns (df_renamed) is then printed for comparison.
