I'm also having issues with getting the gw.cov function to work for fit points.
Here's an example, using the same files...
> pcavars <- names(surveypts[,4:8])
> pcavars
[1] "pca1" "PCA2" "PCA3" "PCA4" "PCA5"
> surv.cov <- gw.cov(data = surveypts, vars = pcavars, fit.points = fitpix, bw
> = surve
I've been running gwr on some survey data and trying to write output back out
to point shapefiles. At first, I thought that the shapefile wasn't being
written, but after calling the file object I found it in a local settings/temp
folder with a random shapefile name. I thought I had specified all

Yes they are: we use the results of real applications as examples

Hi Jeff,
I think you can fit a spatial error model using a glmm in nlme or lme4.
The negative binomial
is not implemented, but a gamma model (if your counts are "well
behaved") should be a good approximation.
Another posibility is to use the VGAM package or mgcv and assume a
smooth surface for your

Agus, I disagree with your claim that R plot functions are not ok for
real applications. Also, I use real applications for learning and
teaching -- they are not fundamentally different.
In the trellis panel functions, or in the direct plot/image/lines etc
functions, you plot in data coordinates
