for example, suppose X is:

1 2 3 4 5 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3 4 2 0 1 2 0 0 0 2 2 2 2 2 ...

and N is 10. I would like a foo(X, 10) to return something like c(6,19) (start and end positions in X of at least 10 consecutive zeros). I can think of a number of slow and probably inefficient ways of doing it (nested loops..), but perhaps someone has a better idea..

Thanks in advance,

Kenn
