[R-sig-Geo] Read HDF files

[janverbesselt]

Please have a look at the example I provided, it should work for your HDF4 files. The MODIS data I am dealing with comes in HDF4 format. I did not need to build a specific GDAL version that supports HDF4 format.
I am using GDAL available via http://www.kyngchaos.com/software/frameworks for Mac OSx, and the latest version of rgdal for R2.13.1. In which environment are your working?
Best,
Jan
