[R-sig-Geo] writeRaster can't find driver

[ElenaC]

Dear all,

having recently updated my versions of R and of the raster library, I'm
encountering problems when writing out geographical data with commands that
previously worked fine. The error appears to be due to "missing drivers":

> require(raster)
Loading required package: raster
raster version 1.9-70 (27-February-2012)
> writeRaster(grid_raster, filename='test.bil', format='EHdr',
> overwrite=TRUE)
Error in .local(.Object, ...) : No driver registered with name: BIL

However the 'EHdr' driver is installed, so I dont really understand why
writeRaster can't find it:
