It is possible to select one subdataset. You must use the name reported in the
lines that contain SUBDATASET_XXX_NAME. For example :

I think support for selecting subdatasets has been added in QGIS 1.8 (I haven't
tested myself, just a vague feeling of having seen a commit message about that)

You can likely directly provide the subdataset name instead of the dataset name.
Not sure if R exposes a way of getting the subdataset names from the dataset.
