winProgressBar will display a progress bar centred on the
screen. Space will be allocated for the label only if it is non-empty.
setWinProgessBar 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, but it
will be garbage-collected once no R object refers to it.
For winProgressBar an object of class "winProgressBar".
For getWinProgressBar and setWinProgressBar, a
length-one numeric vector giving the previous value (invisibly for
setWinProgressBar).
These functions are only available on Windows.
On all platforms,
txtProgressBar, tkProgressBar
pb <- winProgressBar("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))
setWinProgressBar(pb, i, sprintf("test (%s)", info), info)
}
Sys.sleep(5)
close(pb)
