plpanel | R Documentation |
Draw a scatterplot or multibox plot, usuallly after pl.control
and plframe
have been called.
May also be used to augment an existing plot.

The panel function plpanel
draws a scatterplot if both
x
and y
are
numerical, and a multibox plot if one of them is a factor and
ploptions$factor.show == "mbox"
.
Grouping, reference and smooth lines and properties of the points
are determined by the component of plargs
in plpanel
.
This function is usually called by the high level pl functions
plyx
and plmatrix
.
A different suitable function can be used by setting their
argument panel
.
The first arguments, x
and y
,
can be formulas, and an argument data
can be given.
These arguments then have the same meaning as in plyx
,
with the restriction that only one variable should result for
the x
and y
coordinates in the plot.
When frame
is true, plpanel
can be used instead of
plyx
for generating a single plot.
Note that plpanel
does not modify pl.envir
,
in contrast to plyx
.
plpanelCond
shows selected points only and may show
some of them with reduced size and paled color.
It is appropriate for the high level function plcond
.
none
These functions are rarely called by the user.
The intention is to modify ond of them and then call the modified
version when using plyx, plmatrix
or
plcond
by setting panel=mypanel
.

plyx
is essentially a wrapper function of
plpanel
which calls pl.control
and provides additional
features.
plmatrix
also uses plpanel
, whereas
plcond
uses plpanelCond
.
t.plargs <-
pl.control(~Species+Petal.Length, ~Sepal.Width+Sepal.Length,
data=iris, smooth.group=Species, pcol=Species)
t.plargs$ploptions$group.col <- c("magenta","orange","cyan")
plpanel(iris$Petal.Length, iris$Petal.Width, plargs=t.plargs,
frame=TRUE)
