Thanks, Roger. And thanks for alerting me to the possible issues with the
coefficient covariance matrix. For my immediate purposes, this yields
plausible results.

I am trying to run some analysis to determine the percentage contribution
of various factors (minimum temp in lgm, npp, etc) on determining
species richness of 171 species throughout Southeast Asia (on a km by km
basis-so over 4 million rows of cells, and about 14 columns).
I have read about variou
Hi,
How is represented your data: a regular grid: raster, irregular samples:
points, or slots/parcels: areas?
If you want to determine species richness, you can use simpson and shannon
indexes with diversity package.
On a point pattern object, use spatstat::marktable function as mentionned in
h
