[R] which() over a matrix

[javier garcia-pintado]

Hello,
A brief question that I am not able to resolve by my own, but I presume
it's easy for you:

I've used apply to find the values closer to 0 in each row of a matrix:

closer.to.0 <- apply(abs(myarray),MARGIN=1,"min")

My question is how could I use which (or another way) to obtain a vector
that indicates which columns contains these "closer to 0" values?

(I know I can loop, but I mean a faster and elegant way)

Thanks and best regards

Javier
