Hi, I am using the adonis function in the vegan package to determine effects of different environmental factors in forest plant community composition in different regions. I would like to first use adonis to remove the region effect, this is, to fit a model like
adonis_region<- adonis(community ~ region,permutations=999,method="bray") Where community is a presence/absence data matrix of species in forest patches belonging to different regions. Then I would like to use the residuals of this model as the response variable for some other analyses. I know I could use strata to model region as a block variable, but this does not interest me, as afterwards I want to perform another kind of analysis where I would like the region effect to be removed. My problem is that I cannot figure out how to get residual values from the adonis model. Any hint of some other kind of multivariate analysis that could solve this problem is very welcome.
