I don't have a solution to this problem, but as I have also struggled
with what I think is the same problem, I tried to find a small
reproducible example.
The problem seems indeed to be with the progress bar, which will clear
the console after x iterations when the progress bar is called in a
function which is wrapped in a loop. In the example below, this happened
for me every ~44th iteration. Interestingly, it seems that reduction of
the sleep times in this function increases the number of iterations
before clearing.
testit <- function(x = sort(runif(20)), ...)
{
pb <- txtProgressBar(...)
for(i in c(0, x, 1)) {Sys.sleep(0.2); setTxtProgressBar(pb, i)}
Sys.sleep(1)
close(pb)
}
iter = 0
while (TRUE) {testit(style = 3); iter = iter + 1; print(paste("done",
iter))}
Is this only a problem for a few, or is it reproducible? Any hints to
what the problem could be? I have seen this in some versions of R, and
could also reproduce on a freshly installed 3.3.2.
Best wishes,
Jon

Thanks a lot Bert , will check out your suggestions.
I've unchecked the buffer output option in GUI but still have the same problem.
Thanks for your time and concern.

In addition to Jim's comments, which you have not yet satisfactorily
addressed (buffering in GUI??),
1. Show your code!
2. Show ouput of sessionInfo()
3. Upgrade to the latest R version maybe
4. Perhaps write to package maintainer (see ?maintainer) if nothing or
no one helps.
Cheers,
Bert

Thanks for helping Jim.
I'm actually using the pbapply function together with the print function within
a loop. In earlier versions, the progress bar and the output of the print
function used to appear after each iteration of the loop. But with the 3.3.1.
Version nothing appears, instead the console turns white and the cursor turns
blue ( busy) and I know nothing about the progress of the running code.
I just want to see the bar and the output of the print function as I used to,
any help?
Thanks in advance.

A little more information would help. How exactly are out creating the output
to the console? Are you using 'print', 'cat' or something else? Do you have
buffered output checked on the GUI (you probably don't want it checked or you
output will be delayed till the buffer is full -- this might be the cause of
your problem.

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.

Hi all,
I've a question concerning the R 3.3.1 version. I have a long code that I used
to run on versions earlier to the 3.3.1 version, and when I copied the code to
the R console, I can still see the code while the loop is executing , along
with the output printed after each iteration of the loop.
Now, on the 3.3.1 version, after I copy the code to the console, it disappears
and I only see the printed output of only one iteration at a time, that is,
after the first iteration the printed output disappears ( though it's only 6
lines, just giving me some guidance, not a long output).
This is causing me some problems, so I don't know if there is a general option
for R that enables me to still see the code and the output of all the
iterations till the loop is over, as was the case with earlier R versions.
I didn't include the code as it's a long one.
Thanks a lot in advance,
Maram
