Hi
First try updating glibc, and install spgrass6 again. If this does not work
you could try
export MALLOC_CHECK_=0
before you start R. The error might be related to "somewhere something" is
trying to free memory that has already been unallocated. I don't know the
details here, but it could
Hi,
Just upgraded to R 2.9.0 this morning, and tried to update all of my packages.
Everyhing seemed to work, except spgrass6. Manually removing the old packing
and installing fresh resulted in:
install.packages('spgrass6', dep=TRUE)

Hi everyone,
In R, the function lm.LMtests is used to select which spatial model fits
better the data, an error or lag one. It looks to me that there are some
limitations using this function like being constraint to use only
row-standardized spatial weights and it does not support weighted lm ob

I think the error is in .GWR_int line 42:

Can I use gwr for interpolation?
I would for example use something like

data(meuse)
coordinates(meuse) = ~x+y

gridded(meuse.grid) = ~x+y
x = gwr(cadmium ~ dist, meuse, bandwidth = 228, fit.points = meuse.grid)

Hi

This could explain why only the first 155 points are evaluated (in your
example).
