Hi Alexandre,
What type of data are you trying to analyse?
I have analysed environmental data by groups and the script I use looks like follows:
adonis(env~type+biotope, env, perm=9999, method="euclidean")
where type is a list of 5 different environments and biotope is a list of sub-classifications within those environments.
Thank you for your answer Riegardt Johnson, Do you make pairwise comparison between environments and biotope? If yes, please send me your script, my dataset is similar of yours,
Best wishes,
There is some reliable proofreading online service indications for solve weak English for non-native English speakers?
