I am using R 2.8.0 and Windows XP Professional, and the latest version
of spgwr package and the latest versions of spgwr's dependent packages.
In using the gwr function inside of spgwr, I can run it fine until I
input fit points. The x,y fit points matrix I am entering is in the
same form as the coordinates argument. I get the following error
immediately: Error: object "rss" not found. I have spent some time
looking into the gwr function and what the object rss is, but I can't
figure out why this error message comes up and what I am doing wrong.
Can anyone help?

The code, if it helps, is below.
The code always helps, sessionInfo() would too, but I guess that this is
my fault - I noticed the bug in October, but haven't released since then.
If you're in a hurry, I can roll up a Windows binary, otherwise 0.5-5
should get to CRAN soon.
