The problems with the HTML mailing list archives at CRAN should be
fixed now, I have re-created the pages for 2002 using the original
archives from Martin M?chler. r-help and r-devel are now splitted
by month to reduce the size of the index pages a little bit.
Best,

Hello! I am looking for an implementation of the Russell-Rao-Coefficient (Product-Moment-Coefficient). I cannot find it in the usual packages (mva, cluster etc.) And is there already a function for the transformation of matrixes to binary matrixes in R? Hope that this questions are not too trivial or already explained somewhere else, I have not yet got the books.

Hello, and thanks for the two responses to my questions on binary matrixes, which showed me that the functions I needed do not exist. To get a distance matrix with the Russell-Rao-coefficient, I first have to compare each row of a binary matrix with each row and count how many elements are a. equal and b. 1. by f <- function(x,y) (sum(x == 1& y == x)) Now how can I iterate this over a matrix without a loop? I think apply etc. will not work in this case. Thanks for any help.
