Since R 2.1 was released, there is an excellent mechanism for supporting 
off-CRAN repositories including source and if available binary packages. 
Our repository on sourceforge has been running since R-News 5 (1) 
described how to "open up shop". The details for access are on 
http://r-spatial.sourceforge.net -> Download, and include:

> rSpatial <- "http://r-spatial.sourceforge.net/R"
> install.packages("spgwr", repos=rSpatial)

which certainly works for me, also for the Windows binary package (but not
Mac OSX). You do need to install the sp package first from CRAN.

This mechanism does provide a very useful way of making available packages 
that are not quite ready for CRAN, and also allow for providing binaries 
for packages needing special external libraries, which maintainers can 
build against. The disadvantage is that packages on alternative 
repositories are not checked nightly against current R installations, 
unless the maintainers do this themselves.

Note that this release mechanism is more up-to-date than the regular 
sourceforge project page file releases.
