[R-sig-Geo] DEM data in R?

[Felix Andrews]

Hi geophiles,

Anyone know of DEM (elevation grid) data in an R package? I know there
is some bathymetry data in PBSmapping, but I am interested in the land
surface.

Generally, how far is it sensible to go in packaging geographic data
for R? It seems inappropriate for a package to be larger than about
25MB (the size of 'mapdata' package).

But if we are to go beyond coastlines, cities and a few rivers, I
would like to see topographic data available.

Felix
