Details
tkProgressBar will display a widget containing a label and
progress bar.
setTkProgessBar will update the value and for non-NULL
values, the title and label (provided there was one when the widget
was created). Missing (NA) and out-of-range values of
value will be (silently) ignored.
The progress bar should be closed when finished with.
This will use the ttk::progressbar widget for Tk version 8.5 or
later, otherwise R's copy of BWidget's progressbar.
Value
For tkProgressBar an object of class "tkProgressBar".
For getTkProgressBar and setTkProgressBar, a
length-one numeric vector giving the previous value (invisibly for
setTkProgressBar).

controls (which this also does for Tk >= 8.5).

library(tcltk)
# NOT RUN {
<!-- % popups are irritating -->
pb <- tkProgressBar("test progress bar", "Some information in %",
0, 100, 50)
Sys.sleep(0.5)
u <- c(0, sort(runif(20, 0, 100)), 100)
for(i in u) {
Sys.sleep(0.1)
info <- sprintf("%d%% done", round(i))
setTkProgressBar(pb, i, sprintf("test (%s)", info), info)
}
Sys.sleep(5)
close(pb)
