Вот немного побрякушки. От ?tcltk::tkProgressBar
.
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)
