In the `spatstat' package the function density.ppp has an argument
`weights'. This can be used to perform s
Hello,
With rgdal you can access a lot of DEM file formats.
I don't know of any data in available packages, but the volcano dataset is a
very simple one. See the help page for persp() and volcano.
I routinely use the ETOPO2 dataset, but I gather you will want far more
detailed local data than
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 a

Dear list,
I've got two autocorrelated datasets and want to perform a two-sample t-test
comparing the means. Because of the autocorrelation the t-test assumtions
are violated. In Cliff & Ord (1981, Spatial Processes, Ch. 7.2) I read that
there is an alternative modified t-test, which considers
