[R] If loop

[Bert Gunter]

1. I think to get useful help you will have to provide a small
reproducible example. In any case, I was not able to figure out your
problem from what you provided (perhaps others may).

2. R is a (mostly) functional language. It does not have "subroutines" .

Cheers,
Bert
