These are faster than those apply(X, 2, mean) calls
and please do use them when publishing code (both in packages in on this list).

Hello,
I've got an array defined as y <- rnorm(3000), dim(y) <- c(3, 1000).
I'd like to produce a 1000-element vector z that is the mean of the corresponding elements of y (like z[1,1] <- mean(y[1,1], y[2,1], y[3,1])), but being new to R, I'm not sure how to do this for all elements at once (or, at least, simply). Any help is appreciated.
Thanks,
Tom
