Hello, I have a list of vectors (all the same length). How to convert the list to a matrix? Each vector should be a column. I tried this:
l <- list(c(1,2,3),c(1,2,3),c(1,2,3)) mat <- matrix( unlist(l), nrow=length(l) ) But I think this is not very efficient. Is there a better solution? Thanks Markus -- Dipl.-Tech. Math.
