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
