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!
