[R-sig-Geo] Error reading hdf files with rgdal

[Roger Bivand]

When you see an error message from the R interpreter, include the full output, and the output of traceback() issued immediately after the error. Nothing important in raster handling has changed in rgdal. Try to provide a reprodicible example that you can show succeeded on the same system with earlier versions of packages, and which now fail. We cannot see over your shoulder.

Using GDAL and readGDAL both result in the error message:
Error in .local(.Object, ...) :
With no other message following this warning. Trying to use GDALinfo() results in the same warning. I'm having these problems trying to use .hdf files I have previously successfully accessed and transformed to geoTIFF files as well.

Try listing the subdatasets and reading them directly with GDAL or readGDAL
