Passing arguments to iterated function through apply

Question

I have a function like this dummy-one:

FUN <- function(x, parameter){
  if (parameter == 1){
      z <- DO SOMETHING WITH \"x\"}
  if (parameter ==2){
         


        

Answer 1

You can make an anonymous function within the call to apply so that FUN will know what "x" is:

apply(data, 1, function(x) FUN(x, parameter = 1))

See ?apply for examples at the bottom that use this method.
