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
