[R-sig-Geo] reading .hdf files

[Jonathan Greenberg]

Hi Dave:

In all likelihood, it couldn't find your GDAL install.  What OS are
you using?  What GDAL install did you use?  Can you restart R, and
then paste the output of:

library("gdalUtils")
gdal_setInstallation(verbose=TRUE)

And then the output of:

getOption("gdalUtils_gdalPath")

Thanks!
