[R] R Progress Bar

[slomanl1]

I am running Windows 7 64bit. Running a script on Revolution R or R Studio
(the behavior is the same.) The sample script reproduces the problem:

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)

Also, tkProgressBar() behaves the same.
