Pariwise tests in ANOSIM (and/or ADONIS)

I have what I am sure is a very simple question relating to the package vegan, although I have not been able to solve it via Google. Using the function anosim I am only able to produce a global result in the output. Is it possible to produce all pairwise comparisons (corrected) in a single output or are these to be conducted individually? (individual pairwise tests). I guess my question would also relate to the function adonis.
Dear Simon, Pairwise tests are not possible in vegan. My understanding is that the non-R software with such tests makes separate pairwise tests using subsets of data with only two levels of a factor in one tests. We don't provide that in vegan and have no plans to provide this in the future. Cheers, Jari Oksanen
