You want "break". To see the help on this, you need the quotes around it: ?"break", but you don't use them in code, of course. Duncan Murdoch

Type ?"if" at the R prompt, which should load the help page for "Control Flow".

To "break" out of a loop early, use the "break" command (or rethink your logic and use a different type of loop, often if you will be commonly leaving the loop, a while loop may make more sense than a for loop).
