I am using spgrass6, but I can't seem to initiate a grass session. I
managed to do this correctly months ago, but can't seem to now. Here is

This is Exhibit A in my forthcoming case for a spatial data
translation package!

Hello,
Our research group is currently trying to decide on a standard data format
for our modeled climate data (average monthly floating point values for temp
and precip from now until 2099). Our group utilizes R as well as ArcGIS
processing quite a bit, so our goal is to have one format that can

Hello all,
is it possible to define a circular kernel within the function density.ppp(),
that assigns uniform weights to every point inside the kernel.
In this way the attribute 'sigma', would have no meaning, but it could perhaps
be used to define the radius of the (finit sized) kernel in this
HI I am looking for a goodness of fit measure in the case of an
anisotropic variogram model fit in 4 directions. I want to be able to
compare between different fitting algorithms, so a measure that is
independent of the fitting method is key. I also want to compare
between different models (i
