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.superpose.2(..., distribute.type = TRUE)
panel.xyplot
(behaviour in S). To be able to distinguish between different levels of the
originating group inside panel.groups
, it will be supplied
groups
. The default graphical parameters
are obtained from superpose.symbol
and panel.groups
function, which must
know what to do with it. By default, this is
panel.xyplot
panel.groups
, but as scalars rather than vectors. When
panel.groups
is called for the i-th level of g
panel.superpose
from panel.superpose.2
, and to panel.groups
from
panel.superpose
.type
argument.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.
