When I plot my data set in ggplot, I get next to no separation of groups, yet when I run it with Adonis2, I get a p<0.05. What am I doing wrong? I did it before some time ago with a different data set. The difference now is that the new set has relative abundances as fractions of 1 for each species. That should still maintain proportions and make no difference - or does it? Any ideas appreciated!
