For text-based progress bars see the ProgressBar class in R.utils, e.g.
# A "faster" progress bar with default step length 1.4.
pb <- ProgressBar(max=42, stepLength=1.4)
reset(pb)
while (!isDone(pb)) {
x <- rnorm(3e4)
increase(pb)
Sys.sleep(0.02)
}
cat("\n")
Output: [.........|.........|.........|.........|.]
print(pb)
[1] "ProgressBar: max=42, value=42"
See also subclass FileProgressBar, which instead of writing to stdout
writes to a file in way that the file size equals the progress. This
is useful when you batch process jobs in the background and a simple
'ls -l' via ssh or a 'dir' via ftp will tell you the progress of an R
job.
There is also TextStatusBar, e.g. example(TextStatusBar) gives:
...
Processing array.html (3.35kB)
Processing as.data.frame.html (4.23kB)
Processing as.environment.html (1.63kB)
Processing as.function.html (2.28kB)
Processing as.POSIXlt.html (5.97kB)
File: args.html [ 4% 3822 lines 10:10:19]
Hard to explain what it looks like, but try it. (If you run Rgui on
Windows make sure to turn off buffered output).
