R help - Sep 2012 - Inclusion of a countdown tool of remaining calculation time possible?

Dear All, 

We are currently working with very large datasets which even in R require 
a lot of calculation time. Is there an option of including a function/ 
tool or something alike which shows the remaining time of calculation? 
Just to see whether there is any progress or whether anything has crashed 
and to get a feeling whether we have to wait for 5 min or 30min... 

Any help is greatly appreciated! 
Thanks in advance. 
Best, 
Jennifer

?txtProgressBar

  which sounds like exactly what you need.

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.
