[R-sig-eco] different result for permutest (vegan, R) and permdisp (PERMANOVA/Primer)

2016-11-23 Thread Ellen Pape
Dear all, As I want to switch for my multivariate data analyses from PRIMER/PERMANOVA to R, I am comparing all tests I am doing in the former with those performed in the latter program, to see whether results agree. I performed a test for the homogeneity of multivariate dispersions in both

2016-11-18 Thread Ellen Pape
Dear all, I have recently decided to switch from Permanova/Primer to R, because the latter is freeware (and I don't know for how long I will still have a license). However, if I cannot seem to resolve my problem (see below), I might have to go back to using Primer/Permanova. If I run pairwise

Hi all, I don't know whether this is the correct mailing group to address this question: I would like to perform a 2-way permanova analysis in R (using adonis in vegan). By default you are performing sequential tests (by="terms"), so when you have 2 or more factors, the order of these factors
