I have now been enlightened via Windows FAQ 6.2 on "When using Rgui the output to the console seems to be delayed." Ctrl-W toggles whether console output is buffered.
[As a side note: Damn! I was hoping to avoid that response (i.e., having my ignorance pointed out), but all my searches of R-help and FAQs had focused on "for()" and "iteration," which didn't find the right answer. Knowing the "right" question to ask goes a long way...]
Thanks, Dave

I have a somewhat related question. A while back I was doing some simulations using for() loops, and I wanted to keep track of the iterations using a line of code quite similar to what Dimitris presented below. Instead of printing the iteration message at the end of each iteration (actually, at the end of every 100th), nothing was printed until the for() loop was complete, and *then* all the iteration messages were reported. Extending Dimitris' example:
for(i in 1:10000){ x <- rnorm(5) cat("the values of `x' are:", format(x), "\n") cat("computation", i, "finished\n\n") }
demonstrates what I'm referring to (using R v1.9.1 with Windows XP): Iterations are not printed as they occur, only at the end of the for() loop computation.
This *is* in the rw-FAQ. Please see the posting guide.
An interesting wrinkle is that I sometimes use Emacs (and ESS). Running the code from within Emacs prints the iterations as they occur; also, if I switch to other programs and then back to R, iterations have been printed.
