I would like to run the Moran's I on a .img file of forest composition
change categories.  I need to know if I can treat the categories as
independent for performing the two sample Kolmogorov-Smirnov on relative
fire frequency distributions of these forest composition change categories.
Without considering spatial autocorrelation, the fire frequency
distributions of the categories are significantly different according to the
ks-test (which I was advised to use).  It is obvious that these categories
are spatially clustered as are the areas of similar fire frequency, so my
questions/statements are:

1.  Does it make sense to run the Moran's I on the thematic grid data with
R? (Have tried to convert it to vector in both ArcGIS and Imagine and have
run into errors...presumably because of size and complexity?)

2.  I have no idea how to do anything in R (besides the ks-test) and am
completely new to it's spatial tools (although I am keen to learn and have
loaded several of the packages/libraries).

3.  How would I incorporate the p-value results of the Moran's I (if I can
get it to work) into the ks-test of my relative frequencies?

I have ordered the spatial data with R book but I figured I'd cut to the
chase and see if you all could help me get a jumpstart on this.

Thanks ahead of time.
