R help - May 2005 - Tracking progress during iterations

Dear all,
I am using R 2.1.0 for Windows on XP SP2.
In a loop such as below, we can track the progress by a screen print display as
below (in S):

for (i in 1:10){
print(paste("Starting simulation run no...",i))

    result<-c(result,mean(data)) #A dummy example of the simulation to be
done

}

In S-plus environment, the statements

Starting simulation run no...1
Starting simulation run no...2
.
.
.
etc.,

are displayed as the loop is running.  However,
in R, they are displayed only after the loop is completed.
Is there anyway to 'make it' appear as the loop is running?

Thanks in advance.
Best
Lin

See 6.3 of the R Windows FAQ:
http://cran.r-project.org/bin/windows/base/rw-FAQ.html

take a look at rw-FAQ 6.13


I hope it helps.

Best,
Dimitris
