Hello, All:
Does anyone know how to defeat buffering of output to the console
from Rgui? I routinely print progress reports to the console from
within Rterm running under Emacs with ESS (Emacs Speaks Statistics);
see the example below. However, when I run the same example under Rgui,

and ?flush.console .

Dear Prof. Ripley:
Thanks for the reply. Unfortunately, flush.console() seems to
lock up my system. I tried the following:
for(i in 1:1e7){
tst - sin(i)
if((i%%1e5)==0)cat(i, )
if((i%%1e6)==0)cat('\n')
flush.console()
}
This slows down Rgui 2.15.1 (32-bit) by

One of the things that you should learn is how to profile (Rprof) your
code to see where time is being spent. If you did, you would have
seen that all the time is being spent in 'flush.console'. As was
pointed out in a previous response, only call it when something is
printed.

In the R gui for windows you can turn off buffering with cntrl-w or
through one of the menus, but for more general solutions you should
look at:
?flush.console
?winProgressBar or ?tcltk::tkProgressBar or ?txtProgressBar
