The “readline” Function in R

• Package: Base R (No specific package)

• Purpose: To read a line from the terminal (standard input).

• General Class: Input/Output

• Required Argument(s):

• None

• Notable Optional Arguments:

• prompt: A character string to be used as the prompt.

• Example:

• # Example usage
  user_input <- readline(prompt = "Enter your name: ")
  print(paste("Hello,", user_input))

• In this example, the readline function is used to read a line of input from the user with a custom prompt. The user’s input is stored in the variable user_input, and the script then prints a greeting using that input.
