MODIS processing with R, GDAL, and the NCO tools

I use MODIS data for analysis of vegetation dynamics around the world.  The native HDF file format provided by NASA is great for archiving the data (it's amazing how much information they include in each file), but unfortunately there aren't many tools for directly (and easily) extracting data stored across files like there are for the
