x
(and
y
where appropriate) variables are plotted with different
graphical parameters for each distinct value of the grouping variable.panel.superpose(x, y = NULL, subscripts, groups,
panel.groups = "panel.xyplot",
col, col.line, col.symbol,
pch, cex, font,
fontface, fontfamily,
lty, lwd, alpha,
type = "p",
...,
distribute.type = FALSE)
panel.superpose.2(..., distribute.type = TRUE)
panel.superpose
and panel.superpose.2
differ essentially
in how type
is interpreted by default. The default behaviour
in panel.superpose
is the opposite of that in S, which is the
same as that of panel.superpose.2
.panel.groups
gives different
types of plots, for example panel.xyplot
,
panel.dotplot
and panel.linejoin
(This can
be used to produce interaction plots). See Lattice
for an overview of the package.
