ozone

The <code>ozone</code> data is a list of 
components, x and y.  x 
component is longitude and latitude position of each of the 20 
Chicago monitoring stations, y is the average 
daily ozone values over the time period 6/3/87-8/30/87 and lon.lat is 
the longitude-latitude locations of the data.

Fields is a collection of programs for curve and function
 fitting with an emphasis on spatial data and spatial statistics. The
 major methods implemented include cubic, robust, and thin plate splines, 
 universal Kriging and Kriging for large data sets. One main feature is any
 covariance function implemented in R can be used for spatial prediction. 
 There are also some useful functions for plotting and working with 
 spatial data as images. This package also contains implementation of a
 smooth wavelet basis suitable for spatial models.
