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 This is my sessionInfo(): R version 2.9.0 (2009-04-17) i486-pc-linux-gnu locale: LC_CTYPE=en_US.UTF-8;LC_NUMERIC=C;LC_TIME=en_US.UTF-8;LC_COLLATE=en_US.UTF-8;LC_MONETARY=C;LC_MESSAGES=en_US.UTF-8;LC_PAPER=en_US.UTF-8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=en_US.UTF-8;LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] rgdal_0.6-5 sp_0.9-29 loaded via a namespace (and not attached): [1] grid_2.9.0 lattice_0.17-20 tools_2.9.0

Is this a bug?
