Useful Prepanel Function for Lattice

Description:

     These are predefined prepanel functions available in Lattice.

Usage:

     prepanel.lmline(x, y, ...)
     prepanel.loess(x, y, ...)
     prepanel.qqmathline(y, distribution, f.value = ppoints, ...) 

Arguments:

    x, y: x and y values, numeric or factor

distribution: quantile function for theoretical distribution. This is
          automatically passed in when this is used as a prepanel
          function in 'qqmath'. 

 f.value: as used in 'qqmath'

     ...: other arguments

Value:

     usually a list with components 'xlim, ylim, dx, dy', the first two
     being used to calculate panel axes limits, the last two for
     banking computations. The form of these components are described
     under 'xyplot'. There are also several undocumented prepanel
     functions that serve as the default for high level functions,
     e.g., 'prepanel.default.xyplot'
