Apropos, this reminds me of the old quiz (from the S-plus times):

How can you write (quite short!) R code such that

-- without any  "()" -- will quit R (without asking about saving).

[But you shouldn't really keep that code active in your standard R session
 because it would be too easy to accidentally shut down R !]

For the advanced ones: 
My shortest solution uses 51 characters of R code, can you beat that?
