HDF4 in Windows
Doesn't the rgdal binary on Windows come with gdal? http://www.gdal.org/frmt_hdf4.html Though it looks like that driver may be optional at compile time. Not having seen the whole discussion of this, I assume you get some sort of error message trying to load with rgdal? Thanks, Alex

Hi Jonathan, I am using linux/mac (gdal) but did you try: http://fwtools.maptools.org/ for windows? Maybe you can call FWtools (gdal functions) via the:
system() in R?
Alternatively you can use the MODIS MRT tool (windows/linux/mac) to convert to an R raster readable format. https://lpdaac.usgs.gov/tools/modis_reprojection_tool then use gdaltranslate() e.g. to *tif and the raster package to read the geotif. Let us know if this helps because this will be useful for many students here, J Dr. ir.

R-sig-geo'ers: I'm wondering if anyone has made any progress getting hdf4 files working (querying + extracting data) in any R package on *Windows*. I have some MODIS and MASTER files which use HDF that I need to open up and would prefer to not use either an external program or the Linux version of R. Thoughts? --j -- Jonathan A.
