There are a variety of interplation tools to choose from (kriging, splines, inverse-distance-weighting, ...), and a variety of ways to do each of these in R.
For example, have a look at the help page and examples for krige in package gstat, krige.conv in geoR, or Krig in package fields. hth, Kingsford Jones On Thu, Apr 23, 2009 at 7:15 AM, calpeda <mauro.bias...@calpeda.it> wrote: > > Hi all, > > When you want to draw a surface with a mathematics program you need of two > vectors x and y and a matrix z.
