F_2_panel.superpose {lattice} | R Documentation |
These are panel functions for Trellis displays useful when a grouping
variable is specified for use within panels. The 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, fill, font, fontface, fontfamily, lty, lwd, alpha, type = "p", distribute.type = FALSE) panel.superpose.2(..., distribute.type = TRUE)

panel.groups |
the panel function to be used for each group of points. Defaults to
panel.xyplot (behaviour in S).

a grouping variable. Different graphical parameters
will be used to plot the subsets of observations given by each
distinct value of groups . The default graphical parameters
are obtained from superpose.symbol and superpose.line
using trellis.par.get wherever appropriate

type |
usually a character vector specifying what should be drawn for each
group, passed on to the panel.groups function, which must
know what to do with it. By default, this is
panel.xyplot , whose help page describes the admissible
values.

graphical parameters, replicated to be
as long as the number of groups. These are eventually passed down
to panel.groups , but as scalars rather than vectors. When
panel.groups is called for the i-th level of groups ,
the corresponding element of each graphical parameter is passed to
it.

Extra arguments. Passed down to panel.superpose
from panel.superpose.2 , and to panel.groups from
panel.superpose .

logical controlling interpretation of the
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
.

Different functions when used as panel.groups
gives different
types of plots, for example panel.xyplot
,
panel.dotplot
and panel.linejoin
(This can
be used to produce interaction plots).
