Recursion, environment

General
1

I have a task to write four simple funtions in R . One of these functions is a master function with only one argument, which tells how many times the other three functions should be executed. These functions should be executed at random and they should print their own names. The problem is that respectively executed functions should be defined in different environments. To define these functions i should use only global environment and one additionally defined env. How should i apply recursion to this problem?

Typical use

master( 20)

[1] "f1"
[1] "f2"
[1] "f3"
[1] "f1"
[1] "f1"
[1] "f2"
[1] "f3"
[1] "f2"
[1] "f1"
[1] "f1"
[1] "f2"
[1] "f3"
[1] "f3"
[1] "f1"
[1] "f2"
[1] "f1"
[1] "f2"
[1] "f1"
[1] "f2"
[1] "f1"

I have done this so far..., but i don't have any idea how to apply recursion here, and i am not sure if i am doing this task correctly.

new_env<-env()

master<-function(x){
  f1<-function(){
    print('f1')
   }
    master2 <- function(){
        f2<-function(){
        print('f2')
        
      }
      
      los = ceiling(runif(1)*3)
      if (los == 1){
        f1()
      }
      else if (los ==2){
        f2()
      }
      else {
        new_env$f3()
      }
    }  
  
  
  
  
  for (i in 1:x){
      master2()
    }
  }




new_env$f3<-function(){
  print('f3')
  
}
master(20)
