Hi I'm using the raster package to load a DEM from here:
http://www.cec.org/tools-and-resources/map-files/elevation-2007
The data appear to be stored as an ESRI grid (adf) and I have no experience
with this format.

I'm using the raster command (raster package) to read the w001001.adf file:
dem<-raster("./Elevation_GRID/NA_Elevation/data/NA_Elevation/na_elevation/w001001.adf")
The produces what looks like a raster with values. Is that all I need to do or
should I be reading these data another way?
Thanks
Julie
