Dear R friends,
here I write again about the wilcox.exact() problem. I want to compare two sets of categorical data, and in one case it says "negative length vectors not allowed", and in the other one I get the error "cannot allocate vector of length ...". On http://rapidshare.com/files/298621893/wilcox.exact_trouble.Rdata.html you can download the data that cause the trouble. (Attention: 10 Downloads only, so you may have to send me an e-mail so I can mail you the Rdata file directly.) > library(exactRankTests) Package ‘exactRankTests’ is no longer under development. Please consider using package ‘coin’ instead. > wilcox.exact(group_1,group_2,exact=T) Error in .Call("cpermdist2", ma = as.integer(m), mb = as.integer(col), : negative length vectors are not allowed > wilcox.exact(group_3,group_4,exact=T) Error in .Call("cpermdist2", ma = as.integer(m), mb = as.integer(col), : cannot allocate vector of length 1621367542 1621367542 is the same as 2^30.59, so the memory can't be allocated on my 32-bit computer. Can somebody point out the problem to me?
