By the way, I changed metaMDS function in vegan so that it easily accepts unifrac distances a couple of years ago after I was in a workshop with Susan Letcher, and she suggested I do this. Cheers, Jari Oksanen
Would you please point us to any documentation for importing unifrac distance matrices into vegan? (nothing specific about unifrac turns up in the vegan documentation) I was about to do this and was under the impression that i could treat unifrac matrices like any other distance matrix.
Doug, It is not about vegan but about R: vegan uses R dissimilarity/distance structures (that inherit from class "dist"). Once you got it into R it is in vegan, and there is nothing specific to vegan. Cheers, Jari Oksanen
