The “arrange” Function in R

• Package: dplyr

• Purpose: Orders rows of data frames based on column values.

• General Class: Data Manipulation

• Required Argument(s):

• .data: A data frame or tibble.

• ...: Column names or expressions by which to order the data.

• Notable Optional Arguments:

• desc(): A function to arrange in descending order.

• na.last: A logical indicating whether missing values should be placed last. The default is TRUE.

• Example:

• # Example data for arranging rows using dplyr
  library(dplyr)
  
  df <- data.frame(
  ID = c(2, 1, 4, 3, 5),
  Name = c("Bob", "Alice", "David", "Charlie", "Emma"),
  Age = c(30, 25, 28, 22, 35)
  )
  
  # Arrange the data frame by the "ID" column in ascending order
  arranged_df <- arrange(df, ID)
  
  # Display the arranged data frame
  print(arranged_df)

• In this example, the arrange function from the dplyr package is used to order the rows of a data frame (df) based on the values in the “ID” column in ascending order. The result is an arranged data frame (arranged_df). Note that you need to have the dplyr package installed and loaded to use the arrange function.
