Dear list members,
I'm looking for a function in R like the function r.in.xyz in GRASS (vs.
6.2). I have x, y, z data frame (UTM) with z equals depth and would like
to make a 3dperspective plot with rgl. My dataframe has 2.5 milion rows,
so I think it's necessary to convert the data to a grid with something
like mean depth per grid cell. I know I've seen an answer to a similar
question somewhere on one of the lists, but I just don't seem to be able
to find it again. Thanks for any help.
