> Is the webpage not up to date on how to do this? No it isn't, my fault. There was a note in NEWS on this (and it's sister weblink www.bioconductor.org/changelog.html) and the man pages should be updated but I forgot about that special reposTools link. Essentially the first two parameters have switched slots. -J
