[R] Start and Restart R over SSH

[Benilton Carvalho]

Hi Nils,

if the server you're using is *NIX, this is what you can do:

%%%% example
ssh user at server
screen
R

<< do what you need in R>>
<< close the terminal without quitting R >>

ssh user at server
screen -r
<< continue working in R >>
%%%%%% end example

the "problem" is if you need X... it works until you quit the  
terminal, but "screen -r" doesn't reconnect the X11.
