When I exit the interactive R shell, it displays an annoying prompt every time:
> > Save workspace image? [y/n/c]: n
I\'m always answering \"no\" to it
If you are using Rgui, right-click on the icon you use to start R and click on "Properties", and add --no-save to the command that starts R.

If you are using a different editor than Rgui, you have to pass --no-save to the R command line when starting R
