R-alpha: batch

  When is the default going to be changed to not saving the .RData in
batch mode???? Does anyone use batch mode except me?

One rather nasty thing to consider is that interactivity is (as I
understand it) detectable only by the existence of a controlling
terminal. This can cause trouble with cases where the controlling
terminal disappears, one case being upon logout from the windows
system or a system shutdown. Presumably, most people prefer their work
to be saved in those cases.

What might be a much better idea is to make the saving (and loading
too) of .Rdata into command line options, so that

R BATCH filein fileout

would translate into 

R -nosaveimg -noloadimg < filein > fileout
