[R] Computing the rank of a matrix.

    Hi! Maybe this is a silly question, but I need the column rank
(http://en.wikipedia.org/wiki/Rank_matrix) of a matrix and R function
'rank()' only gives me the ordering of the elements of my matrix.
    How can I compute the column rank of a matrix? Is there not an R
equivalent to Matlab's 'rank()'?
    I've been browsing for a time now and I can't find anything, so any
help will be greatly appreciated. Best regards!
