R: [Users] difference between return, break and exit.

[Bogdan-Andrei Iancu]

Hi,

just to be short - it's like in C:
    break - use it only in switch statement
    return  - terminates the current route execution and return in the 
above one
    exit - terminates the script execution disregarding how many levels 
down you are.

regards,
bogdan
