Re: [Rd] Strange behavior when using progress bar (Fwd: Re: [R] The code itself disappears after starting to execute the for loop)

2016-12-12 Thread Jon Skoien 

Thanks John,

As the problem can be reproduced, I would like to submit this as a bug 
report. But I think someone will have to add me to Bugzilla first.
Given the few responses, I am not expecting that this will get a high 
priority though...

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", ...

Yes, I should have clarified, several versions of R, all running on the

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

Now, on the 3.3.1 version, after I copy the code to the console,

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.

[Rd] Strange behavior when using progress bar (Fwd: Re: [R] The code itself disappears after starting to execute the for loop)

2016-11-28 Thread Jon Skoien 
I first answered to the email below in r-help, but as I did not see any 
response, and it looks like a bug/unwanted behavior, I am also posting 
here. I have observed this in RGui, whereas it seems not to happen in 
RStudio.


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

Thanks a lot in advance,

Maram
