The following is what I use frequently, but you should note that the
raster package (assuming that's what you'd like it for) has facilities
built in for progress bar creation:
## NOTE: The tcltk library is used to create a progress bar, but the
## raster package has a progress bar mechanism built in in recent
versions.
## Look up the pbCreate(), pbStep(), and pbClose() functions in
the raster
## package...
require(tcltk)
total_n <- 1000
pb <- tkProgressBar(title = "Predicting Population Density:", min = 0,
max = total_n, width = 300)
for (i in 1:total_n) {
## ...
setTkProgressBar(pb, i, label=paste( round(i/total_n*100, 0),"% done"))
}
close(pb)
