Scatter plot of points

Description

Make or add a scatter plot in a manner coordinated with plotFun.

Usage

plotPoints(
  x,
  data = parent.frame(),
  add = NULL,
  under = FALSE,
  panelfun = panel.xyplot,
  plotfun = xyplot,
  ...,
  plot = trellis.last.object()
)

Arguments

x	A formula specifying y ~ x or z ~ x&y
data	Data frame containing the variables to be plotted. If not specified, the variables will be looked up in the local environment
add	If TRUE, add points as a new layer to an existing plot. If NULL, the value of under will be used.
under	If TRUE, the new layer will be underneath existing layers.
panelfun	Lattice panel function to be used for adding. Set only if you want something other than a scatter plot. Mainly, this is intended to add new functionality through other functions.
plotfun	Lattice function to be used for initial plot creation. Set only if you want something other than a scatter plot. Mainly, this is intended to add new functionality through other functions.
...	additional arguments
plot	a trellis plot, by default the most recently created one. If add is TRUE, new points will be added as a new layer to plot.

Value

A trellis graphics object

Examples

if (require(mosaicData)) {
plotPoints( width ~ length, data=KidsFeet, groups=sex, pch=20)
f <- makeFun( lm( width ~ length * sex, data=KidsFeet))
plotFun( f(length=length,sex="G")~length, add=TRUE, col="pink")
plotFun( f(length=length,sex="B")~length, add=TRUE)
}
