Re: [R] The code itself disappears after starting to execute the for loop

[Jon Skoien]

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

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.

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

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

[R] The code itself disappears after starting to execute the for loop

[Maram SAlem]

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
