  Implementation of Trellis Graphics
}
\details{
  Trellis Graphics is a framework for data visualization developed at
  the Bell Labs by Rick Becker, Bill Cleveland et al, extending ideas
  presented in Bill Cleveland's 1993 book \emph{Visualizing Data} (see
  the references section for details).

  Lattice is an implementation of Trellis Graphics for R. Its interface
  is based on the implementation in S-Plus, although there are several
  differences. Existing Trellis code written for S-Plus should
  \emph{ideally} work unchanged (or with minimal change) in Lattice. One
  exception to this is when custom panel functions are used. See the
  entry for \code{panel} in \code{help(xyplot)} for help with this aspect.

  As of now, most high level Trellis functions in S-Plus have been
  implemented, although the 3d display functions (notably
  \code{wireframe} and \code{contourplot}) are often buggy and
  inefficient.

  Lattice is built upon the Grid Graphics engine for R being developed
  by Paul Murrell and requires the \code{grid} add-on package.

  Type \code{library(help = lattice)} to see a list of (public)
  Lattice graphics functions for which further documentation is
  available. Apart from the documentation accompanying this package, 
  several documents outlining the use of Trellis graphics is available
  from Bell Lab's website that might provide a holistic introduction to
  the Trellis paradigm. Lattice also has a website with some tips.

  Lattice functions, see \code{\link{xyplot}}.

  To learn how to customise the Graphical parameters used by the Lattice
  functions, see \code{\link{lattice.theme}} and \code{\link{lset}}.

  current device, see \code{\link{trellis.device}}

  To learn about sophisticated (non-default) printing capabilities, see

  Here is a list of `high level' functions in the Lattice library with a
  brief description of what they do:

  \bold{Univariate:}  

  \code{\link{barchart}} bar plots

  \code{\link{bwplot}} box and whisker plots

  \code{\link{densityplot}} kernel density plots  

  \code{\link{dotplot}} dot plots

  \code{\link{histogram}} histograms

  \code{\link{qqmath}} quantile plots against mathematical distributions

  \code{\link{stripplot}} 1-dimensional scatterplot

  \bold{Bivariate:}

  \code{\link{qq}} q-q plot for comparing two distributions
  
  \code{\link{xyplot}} scatter plot (and possibly a lot more)

  \bold{Trivariate:}

  \code{\link{levelplot}} level plots (image plots in R)
  
  \bold{Hypervariate:}
  
  \code{\link{splom}} scatterplot matrix
  
  \code{\link{parallel}} parallel coordinate plots
  
  \bold{Miscellaneous:}

  \code{\link{rfs}} residual and fitted value plot (also see
  \code{\link{oneway}})

  See \code{\link{llines}} if you need to write/port nontrivial panel
  functions.
