I read Rnews_2005-2.pdf and I can't do the test.
For instance, on page 10:
maptools and sp are active,

Hello.
In some "geo-spatial analysis" text books & articles,
"boundary effect" was referred.
For spatial weight matrix and its related statistical
methods, this issue is very important, I think.
For this issue, I've looked for this in "spdep" and
"spgwr" in their "manual" pdf files, but no lu

Sorry, no automatic OSX binaries, because of dependence on external

Jacques,
the projection functions are now in package rgdal which is on CRAN so
should have Mac binaries. Look for the function spTransform.
Also, an email I sent to you last night answering a question related to
