If there is more than one conditioning variable,
firstvar specifies which variable to fix first.
mfrow
If there is more than one conditioning variable, mfrow
is passed to par before plotting.
plot.fn
Specifies which plotting function to use: "stacked" results
in stacked conditional densities and "hdr" results in highest density
regions.
x.name
Name of x (conditioning) variable for use on x-axis.
margin
Marginal density of conditioning variable. If present, only
conditional densities corresponding to non-negligible marginal densities
will be plotted.
…
Additional arguments to plot.
Value
If plot.fn=="stacked" and there is only one conditioning
variable, the function returns the output from
persp. If plot.fn=="hdr" and there is only
one conditioning variable, the function returns the output from
hdr.cde. When there is more than one conditioning variable,
nothing is returned.
