R help - May 2013 - interpolation in at least 3, perhaps 4 dimensions?

Hello R-helpers,

I have a data set of points in three dimensions (x, y, z), each with an
associated amplitude. These are data collected using a radar, and of tree
roots.

There are holes in the data, and I'm interested in interpolating the
missing values to create a root map. This could simply be based on
distance, but ideally would also incorporate the amplitude data.

Is anyone aware of an existing implementation of a solution to this type of
problem in R?

Thanks
