> I have a function containing a loop that takes some time to complete.
> Before I enter the loop I want to print a text string to the 
> screen explaining what is being calculated, however, I find 
> that the information is not printed until the function exits. 
> Is there a way of immediately printing a message from within 
> a function as a side effect before it returns?
> 
> code example:
> 
> myFunc <- function(){
>   print.noquote("some message that I want to print before exiting the
> function")
>   j <- 0
>   for (i in 1:1000000){
>     j <- j + 1
>   }
>   j
