[R-sig-Geo] Filling in holes in DTM

[Robert J. Hijmans]

Tobin,

In the raster package you can use the focalNA function. It sets the
focal (neighborhood) value, according to a specified function (e.g.
mean), to cells with NA.

raster is available on R-Forge:  install.packages("raster",
repos="http://R-Forge.R-project.org")
