splom2 {copula} | R Documentation |
A version of lattice's splom
function,
particularly useful for visualizing multivariate data sampled from
copulas, notably nested Archimedean ones.
Experimental We may replace the interface entirely,
for example, to accept an "outer_nacopula"
.
splom2(data, varnames=NULL, Vname="U", xlab="", col.mat = NULL, bg.col.mat = NULL, ...)
data |
numeric matrix or as.matrix(.)able. |
varnames |
variable names, typically unspecified. |
Vname |
character string to become the "base name" of the variables. |
xlab |
x-axis label. |
col.mat |
matrix of colors for the plot symbols (the default is the
setting as obtained from
|
bg.col.mat |
matrix of colors for the background (the default is the
setting as obtained from
|
... |
further arguments, passed to |
from splom()
, an R object of class "trellis"
.
