> To control the progress of a function one can consider to use 
> print() to issue a
> message in the command window. However, using Win98 / R 1.9 
> or WinXP / R 2.0,
> this approach is of little usefulness, since all the print() 
> commands are issued
> at once, just before the control returns to the command 
> window. A test code
> could be:
> 
> for(i in 1:10){
>  for(j in 1:1000){
>   for(k in 1:1000){}
>  }
>  print(i)
> }
> 
> I once ask a linux / unix user and he was not able to 
> reproduce the problem.
