See ?cor.test Also,
rowSums(outer(unique(r1),r1,"==")) gives the number of occurrences of the elements of unique(r1) --- Date: Sun, 01 Feb 2004 16:53:21 -0800 From: Siegfried.Macho <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Subject: [R] 3 little questions Dear R-helpers, 3 questions: 1. Is there a package that contains a routine for computing Kendall's W (coefficient of concordance), with and without ties ? 2. Is there a package that contains a routine for computing Goodman' s Gamma. 3. I there a simple method for computing the number of ties as well as their lengths within a vector fo ranks, e.g. >r1 <- rank(c(1, 3, 2, 3, 3, 2, 4)) gives: [1] 1.0 5.0 2.5 5.0 5.0 2.5 7.0 which contains 2 ties with length 2 and 3.
