"negative length vectors are not allowed" in wilcox.exact() and perm.test()
Dear R friends,
I want to compare two datasets and I get the message
Error in .Call("cpermdist2", ma = as.integer(m), mb = as.integer(col), :
negative length vectors are not allowed
after specifying the exact test. I'm using the exactRankTests package. Do you suggest me using the coin library, or is there anything "wrong" with my data?
Kind regards,
David
