[STATSGRASS] making R and grass(6.1) play well together.

[Tom Colson]

Thanks for the quick reply. 

I did install spgrass6 and all its dependencies and have managed to
reproduce this:

> library(spgrass6)

> G <- gmeta6()

> dem <- readFLOAT6sp("ncfpm_2694")



Specifically, though, I am seeking how to import the raster DEM into
some sort of format that the stats library will recognize so I can plot
the ecdf cruves......ie..

library(stats)
plot(ecdf(dem))
plot(ecdf(dem), verticals=T, do.points=F)
