Unifrac distance matrix with dbRDA in Vegan
Hi Jari, Thanks. That's what i thought, but i was confused by this: "I changed metaMDS function in vegan so that it easily accepts unifrac distances" I thought it was something to do with formatting or a special unifrac output file or something. doug

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.
