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.

house1.sel<-gwr.sel(house$consideration ~ house$total_living_area +
house$waterfront + house$grade_recode + house$effective_age +
house$accepted_acreage + house$major_infl_amt, data=house, housecoords,
adapt=TRUE);

house1.gwr<-gwr(house$consideration ~ house$total_living_area +
house$waterfront + house$grade_recode + house$effective_age +
house$accepted_acreage + house$major_infl_amt, data=house, housecoords,
adapt=house1.sel, fit.points=xys, se.fit=TRUE);
