The “do.call” Function in R

• Package: Base R (no specific package required)

• Purpose: Calls a function with a list of arguments.

• General Class: Functional Programming

• Required Argument(s):

• what: A function to be called.

• args: A list of arguments to the function.

• Notable Optional Arguments:

• None

• Example:

• # Example data for using the do.call function
  function_name <- "sum"
  arguments <- list(1, 2, 3, 4, 5)
  
  # Use do.call to call the 'sum' function with the provided arguments
  result <- do.call(what = function_name, args = arguments)
  
  # Display the result
  print(result)

• In this example, the do.call function is used to call the sum function with the provided arguments. The function_name variable is a character string specifying the function, and the arguments variable is a list of arguments to be passed to the function. The do.call function is useful in situations where the function and its arguments are dynamically generated or stored in variables.
