problem with function project() in package rgdal

Hi Renaud,

I don't get the same error, the piece of code runs fine. To which 
version of proj did you build rgdal? My versions are:

Geospatial Data Abstraction Library extensions to R successfully loaded
Loaded GDAL runtime: GDAL 1.4.4.0, released 2007/11/23
Path to GDAL shared files: /usr/share/gdal
Loaded PROJ.4 runtime: Rel. 4.6.0, 21 Dec 2007
Path to PROJ.4 shared files: (autodetected)

Googleing for "major axis or radius = 0 or not given" will give you some 
useful things to start with.

As a remark, I always transform my spatial data to sp-classes (using 
coordinates() or gridded(), see sp-docs) and then use spTransform to 
perform the reprojection.

cheers,
Paul
