I think you do not understand how the parallelization works: Different
iterations from your foreach() are run on different nodes, hence you
change the progressbar on the node rather on the master in your loop.

Hi all,
I can create a text-progress bar in a foreach loop by the following code :
n=10
foreach( i = 1:n ,.combine=c) %do%{
setTxtProgressBar(pb, i)
Sys.sleep(0.1)
}
However, once i use the parallelized foreach, the text-progress bar
disappear. Any solution to this problem? How can i create a progress
bar in parallelized foreach? Thanks
cl<-makeCluster(core)
registerDoSNOW(cl)
pb<-txtProgressBar(min = 0, max = n, style = 3)
foreach( i = 1:n ,.combine=c) %dopar%{
setTxtProgressBar(pb, i)
Sys.sleep(0.1)
}
close(pb)
stopCluster(cl)
Regards,
TszKin Julian
