Hello List,
I have two questions.
1.) How do I generate a matrix of residuals in RDA (I am using rda() in
vegan)?
2.) How can I test for spatial dependence (spatial autocorrelation) in the
response matrix of a multivariate analysis (RDA in my case)? I have read that
you can look at the trace of the variogram matrix as a multivariate alternative
to Moran's I, but I don't know the details of how to make this test happen
using R.
Thanks for any help!
Tracy
