ok, After the correct installation of the new release with: cvs -z3 -d:pserver:rgdal.cvs.sourceforge.net:/cvsroot/rgdal co -P rgdal R CMD INSTALL rgdal
I can confirm that the new argument works fine: > require(rgdal) Loading required package: rgdal Geospatial Data Abstraction Library extensions to R successfully loaded Loaded GDAL runtime: GDAL 1.6.3, released 2009/11/19 Path to GDAL shared files: /usr/share/gdal16 Loaded PROJ.4 runtime: Rel. 4.7.1, 23 September 2009 Path to PROJ.4 shared files: (autodetected) > packageDescription("rgdal") Package: rgdal Title: Bindings for the Geospatial Data Abstraction Library Version: 0.6-27 Date: 2010-05-11 .../... > terNOXLC <- > readOGR(dsn="/media/TRANSCEND/MASTER_ICTA2007_2008/miniproj_GISInP2009/MARICEL2", > layer="terNOX0709buf2500values",stringsAsFactors=F) OGR data source with driver: ESRI Shapefile Source: "/media/TRANSCEND/MASTER_ICTA2007_2008/miniproj_GISInP2009/MARICEL2", layer: "terNOX0709buf2500values" with 4100 features and 12 fields Feature type: wkbPoint with 2 dimensions > class(terno...@data[,1]) [1] "character" > terNOXLC <- > readOGR(dsn="/media/TRANSCEND/MASTER_ICTA2007_2008/miniproj_GISInP2009/MARICEL2", > layer="terNOX0709buf2500values",stringsAsFactors=T) OGR data source with driver: ESRI Shapefile Source: "/media/TRANSCEND/MASTER_ICTA2007_2008/miniproj_GISInP2009/MARICEL2", layer: "terNOX0709buf2500values" with 4100 features and 12 fields Feature type: wkbPoint with 2 dimensions > class(terno...@data[,1]) [1] "factor" > terNOXLC <- > readOGR(dsn="/media/TRANSCEND/MASTER_ICTA2007_2008/miniproj_GISInP2009/MARICEL2", > layer="terNOX0709buf2500values") OGR data source with driver: ESRI Shapefile Source: "/media/TRANSCEND/MASTER_ICTA2007_2008/miniproj_GISInP2009/MARICEL2", layer: "terNOX0709buf2500values" with 4100 features and 12 fields Feature type: wkbPoint with 2 dimensions > class(terno...@data[,1]) [1] "factor" Many thanks!
