Subject: Two-Way PERMANOVA with Repeated Measurements
Hello,
I want to perform a permanova where the first factor called Treatment
has four levels. The second factor involves sampling the same research
plots for four consecutive years, hence the repeated measurements.
I have been able to use the adonis function from the package vegan to
run this analysis.
code below:
TC.perMANOVA.adonis<-adonis(TC.PerMANOVA ~ Treatment*Year,
data=TC.PerMANOVA.ENV, permutations=99, method="bray", strata = NULL)
However, my concern is that this does not take into account that Year
is a repeated measurement on the same research plots.
Any suggestions would be appreciated.
