...ame (character) and Age (numeric). Now when I unlist l, I obtain : unlist(l) Name1 Name2 Age1 Age2 Name1 Name2 Age1 Age2 1 2 1 2 1 2 3 4 Is there a way to at least obtain something like A 1 B 2 C 3 D 4 as result from the unlist??

Dear all, I would like to know if there is an easy to transform a vector of strings to a vector of integers. Ex: ("ab","ab","bb","cat","cat","ab") will be (1, 1, 2, 3, 3, 1) Thx, Naira -- View this message in context: http://www.nabble.com/From-strings-to-numbers-tp17315179p17315179.html Sent from the R help mailing list archive at Nabble.com.

Dear All, a short and maybe simple question: I have to rank all values in a matrix from 0 to X, [1] [2] [3] [4] [1] 0.1 2 0 3 [2] 50 3 3 1 [3] 100 1 1 0 [4] 100 2 2 0 0->0 0.1->1 2->2 3->3 50->4 100->5 (X=5) is there any function for this? i have looked in several packages (vegan, labdsv etc.) because I am working with species by site tables,
