R help - Oct 2014 - how to break the loop using sapply?

Dear expeRts,
?? i? use sapply for loop,?and i want to break it when i needed, how to do
that?? e.g.

sapply( 1:10, function(i) {
if(i==5) break and jump out of the function sapply
} )

I want to do it because i have to loop 1000000 times, but i don't know when
it will break, that means, it may need break at i=5 or at i=50000, for the
possible of the? last case, i don't use for loop, because it slow(is it
right?).
So,if you happen to know it ,may you help me?

Don't use apply functions if you want to do what you describe. They
don't work that way. Use a while control structure.
