Hello all,
I am an undergraduate, so bare with me if I don't make complete sense!
I have performed a permanova using the function Adonis (vegan), to test for
significant difference in OTU datasets from different species (n=5) at
different sites (n=6) with a total of 20 libraries (unbalanced). I have got a
significant result, but I would like to know which species/ sites are causing
this result.
adonis(formula = vegdist(comm, method = "bray") ~ Species, data = metadata,
strata = Site)
I have heard you can run multiple adonis tests, and then adjust the P value
(which correction?), although I am not sure my reduced datasets meet the
assumptions, or if the permutations produce a meaningful result at such a low
number.
Does anyone know how to get around this, or if I should be using a different
test for this data?
Thank you in advance,
Hazel Knipe
