\title{Scatterplot Matrix [SPLOM] With Nice Variable Names}
\description{
A version of \pkg{lattice}'s \code{\link{splom}} function,
particularly useful for visualizing multivariate data sampled from
copulas, notably nested Archimedean ones.
\bold{Experimental} We may replace the interface entirely,
for example, to accept an \code{"\linkS4class{outer_nacopula}"}.
}
\usage{
splom2(data, varnames=NULL, Vname="U", xlab="",
col.mat = NULL, bg.col.mat = NULL, \dots)
}
\arguments{
\item{data}{numeric matrix or as.matrix(.)able}
\item{varnames}{variable names, typically unspecified}
\item{Vname}{character string to become the "base name" of the variables}
\item{xlab}{x-axis label}
\item{col.mat}{matrix of colors for the plot symbols (the default is the
setting as obtained from \code{\link[lattice]{trellis.par.get}("plot.symbol")$col}).}
\item{bg.col.mat}{matrix of colors for the background (the default is the
setting as obtained from \code{\link[lattice]{trellis.par.get}("background")$col}).}
\item{\dots}{further arguments, passed to \code{\link[lattice]{splom}()}.}
}
\value{from \code{\link{splom}()}, an \R object of class \code{"trellis"}.
