Scatter plot of points

Source: R/plotPoints.R

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

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

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)
