I wrote a little stopwatch function that ticks elapsed time for an
expression, you can find it here:

but it has no way of knowing how long your process is going to take.
If you have something like a loop from 1:N you can do progress bars -
assorted ones are provided by the packages utils, tcltk, R.utils and
plyr - install them and do ??progress for a list of functions.
