fields

fields is a contributed package to the R Project for Statistical Computing and is a suite of well documented functions focused on fitting curves and surface to irregular data. The major methods implemented include cubic and thin plate splines, universal Kriging and Kriging for large data sets. There are also some useful functions for plotting and manipulating fields on regular grids.
