In general, is it possible to run R scripts through cron jobs ?
Yes, the only problem might be if you use anything that needs a
graphics window. In the old days you needed an X11 display to create
png graphics with the png() function, but not any more. I'm not sure
if yo need an X11 system for anything apart from showing graphs. But I
don't know everything.
Some package authors assume such a display to install their packages
(and a few of those may not have a choice as some graphics libraries
seem to need one to be loaded). So my dept's automated package updater
scripts run from cron, and start (and stop) a Xvfb X server to get
around that.
