Re: [Rd] Strange behavior when using progress bar (Fwd: Re: [R] The code itself disappears after starting to execute the for loop)
I would like to ask once more if this is reproducible also for others?
If yes, should I submit it as a bug-report?
Best,
Jon

Similar to OP, I sometimes have a problem with functions using the
progress bar. Frequently, the console is cleared 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.
In my real application, where the progress bar is used in a much
slower function, the console is cleared every 2-3 iteration, which
means that I cannot scroll back to check the output.
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, or if it can be fixed? I have seen this in
some versions of R, and could also reproduce in 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.

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 thecursor 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 mightbe 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 ( thoughit'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 allthe 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

Please Windows users .. this is possibly only for you!
Note that I do *not* see problems on Linux (in ESS; did not try RStudio).
Please also indicate in which form you are running R.
Here it does depend if this is inside RStudio, ESS, the "Windows
GUI", the "Windows terminal", ...

Re: [Rd] Strange behavior when using progress bar (Fwd: Re: [R] The code itself disappears after starting to execute the for loop)
Dear Martin and Jon,
I can reproduce this problem in the Windows GUI, where I observed it using
Jon's program after 75 iterations. I didn't observe the problem in a Windows
terminal or under RStudio, letting the program run for more than 200 iterations
in each case.
