beta diversity and permutation analysis

[bioinfonext]

I have done beta diversity analysis using phyloseq PCoA on rarefying OTU data with bray distance and now for statistical significance, I want to use adonis function from vegan so should I use the same rarefying table in vegan with below command:

pmv =adonis(werra_sp_rerefy ~ Region, data= werra_env, permutations = 999, method = 'bray')

Is it be Ok or should I do PCoA analysis in vegan itself?

I am not sure how to do PCoA analysis in vegan? could you please suggest the command for it?

thank
