R help - Oct 2010 - one function with 2 returnh points

Hello everyone.
I have written quite a big function that at the end correctly returns the values
I want. I found a rare exception that I want to cover also. The easier for me 
would be to write something like that


function(){
    
  if (rare exception happened)
      return that value

  # The comes the code for normal execution
  # ...
  # ...
  return value # Normal values to return

}



Would that be feasible with R or two returns statements are not accepted?

Regards
Alex

Are you looking for something similar?
fun <-
    function(x)
{
    if(is.character(x)){
        return(paste('Error: wrong!'))
    }
    res <- sum(1:10)
    return(res)
}
> fun('asdf')
[1] "Error: wrong!"
> fun(1:10)
[1] 55
