Thanks, sorry - my mistake, I thought you meant 'load' as in visit the
file, but you (rightly) meant ess-load-file.  Yes, I see the error that
you do.  Is it anything to do with missing \n from the cat statement?
Probably the code that looks for the prompt is getting confused.

i.e this works 

  cat("Done!!!")
  cat("\n")
