Running R Remotely on LINUX
Hi Michael,

Since some of my computations are taking a lot of time I am now trying to move to a remote R session on a LINUX server but I am having trouble to getting things work. I am able to access the LINUX server using PuTTY and SSH. Once I have access I can log in with my username and password (which is asked through keyboard-interactive authentication). I can then open an R session. Since I am not used to working with LINUX, I have several questions: (1) Ideally I am looking for a Windows-based software that would allow me to work on R as I am used to with the difference that the computations are run remotely on the LINUX server. Does a software like this exist? Please note that I do not think that I can install any software on the LINUX server. But I can install stuff on my Windows-based PC.
Can't help you on the windows side
(2) I am running an extensive simulation that takes about one week to run. Right now it seems that when I log out of R on LINUX and close PuTTY, the R session closes as well. Is there a way to let R run in the background for the week and just check into the progress 1-2 times a day?
There is "screen", a utility that acts as a layer between your login and the actual shell(s) you open. It allows to detach from and reattach to a session and would nicely fit this requirement. I'll assume you are not producing any graphics output to screen, that would be difficult.
(3) Can I open several instances of R in parallel? On my PC I sometimes have 2-3 windows open in parallel that work on different calculations to save time. Not sure to which extent this is possible on LINUX.
2 or 3 should be no problem - you'll only be limited by memory (and cores to stay efficient). open as many connections (or consoles in screen) as needed and start an R in each.
I assume that this questions are very na?ve. But since I?m only used to working with Windows I?m quite stuck at the moment. Any help would be very appreciated! Thanks in advance, Michael Michael Haenlein Professor of Marketing ESCP Europe [[alternative HTML version deleted]]
