Hi!
I needed different .RData files for different computers linked via nfs
in
order not to overwrite configurations. I did the following:

".First" <-  function ()
{
  image <- paste(".RData.",Sys.getenv("HOSTNAME"),sep="")
  print("restoring session <",image,"> ...")
  load(image,globalenv())
  if (interactive()) options(error=quote(dump.frames())) 
  else options(error=quote({dump.frames(to.file=TRUE); q()})) 
  options(warn=1)
  gc()
}
