[R-sig-Geo] get rgdal to read ENVI raster?

[Felix Andrews]

Hi,

I am trying to use rgdal to read in an "ENVI .hdr labelled raster"
--see http://www.gdal.org/frmt_various.html#ENVI
but GDAL uses the wrong driver, "ESRI .hdr labelled"
--see http://www.gdal.org/frmt_various.html#EHdr

So the imported grid data is just noise.
I can not figure out how to make GDAL/rgdal use the ENVI driver.
Suggestions would be appreciated.

The .hdr file contains:
NCOLS      200
NROWS      200
XLLCORNER    148.50000000000
YLLCORNER   -37.002500000000
CELLSIZE    0.10000000000000E-01
NODATA_VALUE   -9999.000
