how do I check the rank of a matrix ?


A= 1 0 0

     0 1 0

then rank(A)=2

what is this function?


  I did try help.search("rank"), but all the returned help information seem irrelevant to what I want.

  I would like to know how people search for help information like this.

rank(base)              Sample Ranks
SignRank(stats)         Distribution of the Wilcoxon Signed Rank
Wilcoxon(stats)         Distribution of the Wilcoxon Rank Sum

kruskal.test(stats)     Kruskal-Wallis Rank Sum Test
                        Pairwise Wilcoxon rank sum tests
wilcox.test(stats)      Wilcoxon Rank Sum and Signed Rank Tests
