[R-sig-Geo] advice on spatial regression for interpolated data

[juanita choo]

Hi Everyone,

I am trying figure out the best method/R package for analyzing my
data. I am testing the hypothesis that seedling density data is
correlated with both adult tree densities and seed predation
intensities. I have mapped out the locations of all adult and
seedlings in a 150x150m plot, and have estimated predation intensities
at  72 locations in the plot. All variables are spatially
autocorrelated. I was planning running a spatial regression on the
interpolated values seedling densities (dependent variable) against
adult densities, and predation intensities. But I am not sure if this
is appropriate or if there is a better method. I was looking at the
spdep package was wondering whether the lagSARlm would work in this
setting. Thanks for your advice on this.
