The “unite” Function in R

• Package: tidyr

• Purpose: To unite multiple columns into a single column by concatenating their values.

• General Class: Data Reshaping

• Required Argument(s):

• data: The data frame to reshape.

• col: The name of the new column to create.

• ...: Names of columns to unite.

• Notable Optional Arguments:

• sep: The separator to use between values. The default is “_“.

• Example (with Explanation):

• # Load necessary packages
  library(tidyr)
  
  # Create a sample data frame
  data <- data.frame(
  ID = 1:3,
  First = c("John", "Jane", "Bob"),
  Last = c("Doe", "Smith", "Johnson")
  )
  
  # Unite the 'First' and 'Last' columns into a single column 'Name'
  result <- unite(data, col = "Name", First, Last, sep = "_")
  
  # Display the result
  print(result)

• In this example, the unite function from the tidyr package is used to reshape the sample data frame data by uniting the ‘First’ and ‘Last’ columns into a single column ‘Name’. The values from the ‘First’ and ‘Last’ columns are concatenated with _ as the separator. The result is a new data frame result containing the reshaped data with the specified columns united into a single column.
