I am currently learning how to work with a new shared computer (a Mac pro) in
our lab, that is dedicated to execute R code for large simulations (over a
few days).
We have a VNC option to remote control the computer, with a shared used
session, but this is not really needed in most of the cases. I would like to
do some ssh access.
This is pretty straigthforward, and I am able to launch commands using
R -e 'source(myfile.R)'
However, it could be useful to check the advancement of the computation from
time to time, again via ssh.
Is there any way to do this?
On Linux you can type in the terminal (I guess the command will
work in Mac too):
tail -f myfile.Rout
Then you hit Ctrl+C to stop tail from following myfile.Rout.
Another option would be the use of screen (again, this is a *nix
solution that may be available to Mac too). With screen you can
run R interactively detach the session, logout, come back and
reattach the session. But it seems that tail -f is what you
really needs since the R script is finished and you just need to
run it.
