R help - Oct 2009 - "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

Yes. You did not show your data.
