[R] Start and Restart R over SSH

[Nils Höller]

Hi,
 
I have some big calculations in R to be done. 
Since I can use R on a server with ssh, i was wondering if I can reopen
a R Shell after exiting ssh.

I don't want to use the batch mode and nohup doesn't work.

I want to use something like
ssh user at server
R
---do something in R and start calculation ---
close ssh but let R remain on the server, doing the calculation

ssh user at server
open the existing R Shell / Process

Has anyone done something similiar?
Can you help me or suggest an other solution ? 

Thank you for your help

Nils
