\title{Simulation and Analysis of Random Fields}
\description{
  The package \code{RandomFields} allows for simulating various kinds
  of random fields.  The emphasis is (still) on unconditional simulation
  of stationary and isotropic
  Gaussian random fields, but the package provides also basics for
  conditional simulation of Gaussian random fields.  Furthermore,
  non-Gaussian random fields, i.e.
  max-stable random fields, can also be simulated.
  
  Additionally, the package provides tools for analysing spatial data,
  namely the calculation of the empirical variogram, interactive
  fitting of a variogram model, and the MLE estimation of variogram
  parameters. A very few, basic, kriging procedures are also provided.

  Diverse extensions of the package are planned.
