Hi. I am new to R and facing a problem that I cannot solve.

 

I am writing some basic functions. Then I would like to have a master function that allows me to call one of the functions which I created, but I cannot figure out how to do so.

 

Below is an example. The functions rnormIra and runifIra both seem to work fine. I do not get an error message when entering the definition of the master function randomIra; however, it fails when I use it to call another function.

 

Can someone please help?

 

Thanks.

 

Ira



rnormIra = function(n, mean) {
  return(rnorm(n,mean,1))
}
rnormIra(10,100) #works fine



runifIra = function(n,min,max) {
  return(runif(n,min,max))
}
runifIra(5,20,30) #works fine



randomIra = function(f, ...) {
  if(f == rnormIra) {
   return(rnormIra(n,mean))
  }
  else {
        return(runifIra(n,min,max))
  }
} #no error messages



randomIra(rnormIra, n = 5, mean = 20) #FAILS
randomIra("runifIra", n = 5, min = 10, max = 25) #FAILS

do.call(randomIra,list("rnormIra",5,20)) #FAILS
