Hmm
I'm trying to work with gpclib, converting to and from the sp classes.
I don't know what is/was in the package spgpc, but it is no longer
available:
> install.packages("spgpc", repos=rSpatial)
Warning: unable to access index for repository
http://r-spatial.sourceforge.net/R/bin/windows/contrib/2.5
The page http://r-spatial.sourceforge.net/xtra/xtra.RHnw.html says:
"the functionality described here has been included in packages rgdal,
naptools, and spgrass6, now all on CRAN. This page is maintained for
documentary purposes only, and most of the examples shown here are the
examples used in the released packages."
where i'm guessing "naptools" should be "maptools".
But I can not find a method to coerce between "gpc.poly" and
"Polygons" classes. Not that it is difficult to manually... just
wondering.
