I'm new to the R language and the packages therein. What I wanted to know
is if there are any way to obtain additional diagnostic info such as log
likelihood or r square in the gstsls function in the spdep package. I have
searched the documentation and have largely come up empty handed.
Hi,
I have gis point data of plant volumes, I wish to interpolate from these points
to give me a shape file/raster of volumes across my study area (I was thinking
of using spatial analyst tools (kriging interpolation) in ArcGIS.
In addition to the point data I have probability of plant occur

Marco,
I just took a look at the data; unfortunately, it's not in a very usable format
without reformatting it for
importing the data into either R or a GIS, such as GRASS GIS. I'm sure an

write a clever R script to do what you want. Personally, I would write a
