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){}

I once ask a linux / unix user and he was not able to reproduce the problem.
