Since the format is raw binary it would be easy enough to read the raw values with ?readBin and construct a Spatial object from that. If there is sufficient metadata with the files it might already be recognized by a GDAL, and if you are lucky in turn by your build of rgdal (I've not checked the file sets).
Doing it manually is straightforward but laborious and error-prone, another option is to use the GDAL VRT format - where you can formalize all of the data type, georeferencing, projection and other metadata (scaling and so on if necessary) - the you can more or less automate the process by generating a .vrt for any of the files you like (and you can include subsetting, combining single to multi-bands, scaling etc. in the VRT definition). http://www.gdal.org/gdal_vrttut.html VRT is surely almost always available in any rgdal/GDAL build since it's so generic. I don't have time to attempt this now, but I know it can work. Cheers, Mike.
