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
Hi Tracy,
You can try this:
require (vegan)
data(mite)
data(mite.env)
data(mite.xy)
mod- rda (mite~., data=mite.env)
res-residuals(mod)
require (spacemakeR)
vario-variogmultiv(res, mite.xy)
plot(vario$d, vario$var, ty='b',pch=20,xlab=Distance, ylab=C(distance))
But, I'm not sure. Maybe to
Dear Tracy,
You can see if Helene Wagner's mso() in function in vegan satisfies your needs
for analysing spatial dependence. Reference and further description in ?mso.
Cheers, Jari Oksanen
