R help - Jul 2010 - Printing status updates in while-loop

Dear all,

I'm using a while loop in the context of an iterative optimization
procedure. Within my while loop I have a counter variable that helps me to
determine how long the loop has been running. Before the loop I initialize
it as counter <- 0 and the last condition within my loop is counter <-
counter + 1.

I'd like to print out the current status of "counter" while the
loop is
running to know where the optimization routine is standing. I tried to do so
by adding print(counter) within the while loop. This does however not seem
to work as instead of printing regular updates all print commands are
executed only after the loop is finished.

Is there some easy way to print regular status updates while the while loop
is still running?

Thanks,

Michael

try:

print(counter)
flush.console()  # force the output
