Correct me if I am wrong, but it is my impression that GDAL does not support names for bands; so there would be to directly write these via (r)gdal. I am not sure if GeoTiff supports the concept. In the case of ENVI, I suppose it would be possible to add the band names to the hdr file; but the raster package currently does not do that. Robert
