[R-sig-Geo] Help with gpclib

[O'Hanlon, Simon J]

Dear Manuel,
I am also running R2.15.1 on Mac OS X 10.7.

I get:
> library(maptools)
Loading required package: foreign
Loading required package: sp
Loading required package: lattice
Checking rgeos availability: TRUE
> library(rgdal)

Perhaps you can try updating to the latest rgeos release? And maybe try updating your rgdal from the kyngchaos website (if it isn't already the latest version)?

HTH,

Simon

Dear list members,

I am running R 2.15.1 on a MAC OSX 10.7.

I receive an error message regarding gpclib (see below):

> library(rgdal)
> library(maptools)
> library(rgeos)
Loading required package: stringr
rgeos: (SVN revision 330)
 GEOS runtime version: 3.3.2-CAPI-1.7.2

 WARNING! if you turn polygon checking off, and polygons are
 not valid in GEOS, you risk losing data as your R session may crash!

> indice <- readOGR(".", "indicesalud2007crtm")
OGR data source with driver: ESRI Shapefile
Source: ".", layer: "indicesalud2007crtm"

> map <- fortify(indice)
Using NCANTON to define regions.
Error: gpclib, maptools package required for this functionality.  Please
