I am encountering errors when attempting to run the example(gwr) in the
spgwr package. The first 4 commands run correctly, however I receive an
error trying to execute the 5th command.

gwr> data(columbus)

gwr> col.lm <- lm(crime ~ income + housing, data = columbus)

gwr> summary(col.lm)

gwr> col.bw <- gwr.sel(crime ~ income + housing, data = columbus,
    coords = cbind(columbus$x, columbus$y))

gwr> col.gauss <- gwr(crime ~ income + housing, data = columbus,
    coords = cbind(columbus$x, columbus$y), bandwidth = col.bw,
    hatmatrix = TRUE)
Error in gridded(fit.points) : No direct or inherited method for function
"gridded" for this call

I'm running the following configuration on Windows XP.
Windows R 2.0.1
Windows Binary sp_0.7-0.zip
Windows Binary spgwr_0.2-7.zip

Any guidance would be appreciated.

Ken
