I have a function with an structure like this:

 function(x, y, z, n = 3){
  
  test = #funky fit with the input data
  
  other = #more metrics 
  
    #conditions to evaluate the model
  if (condition1 = TRUE){ #condition based on other or test
    #rerun function with n = 2
  } else if (condition2 = TRUE) {#condition based on other or test
    #rerun function with n = 1
  } else {
    #save the output
  }
    
}

I'm wondering how can I re run the function when condition 1 or 2 are met changing n to 2 or 1 respectively. I am aware of while but I'm not sure how to implement it on this situation.

Why not just use recursion?

recurse = function(x, y, z, n = 3){
  test = #funky fit with the input data
  other = #more metrics 
  
  if (condition1){
    recurse(x, y, z, n = 2)
  } else if (condition2) {
    recurse(x, y, z, n = 1)
  } else {
    # Choose the return value here
    other
  }
}
