bubbleplot: Bubbleplots

In tactile: New and Extended Plots, Methods, and Panel Functions for 'lattice'

Bubbleplots

Description

Draws bubbleblots – trivariate plots where the third dimension is mapped to the size of the points drawn on the screen.

Usage

bubbleplot(x, data = NULL, ...)

## S3 method for class 'formula'
bubbleplot(
  x,
  data = NULL,
  maxsize = 3,
  bubblekey = TRUE,
  panel = panel.bubbleplot,
  groups = NULL,
  subset = TRUE,
  drop.unused.levels = lattice.getOption("drop.unused.levels"),
  ...,
  outer,
  allow.multiple
)

Arguments

x	A formula of the form z ~ x * y, where x and y have the usual interpretation in trellis graphics (see lattice::xyplot()) and z is mapped to the size of bubbles.
data	A data.frame, list or environment wherein the formula and groups arguments can be evaluated.
...	Further arguments to pass to lattice::xyplot().
maxsize	Maximum size (in cex) for the bubbles.
bubblekey	Set to TRUE to draw an informative legend about the bubbles. Uses lattice::draw.key(). See the key section of the documentation in lattice::xyplot(). If both auto.key and bubblekey are given and their space arguments (positions) conflict, bubblekey will silently override the position of auto.key.
panel	See lattice::xyplot(). Here, we are passing an additional variable, z, which is then used in panel.bubbleplot().
groups	See lattice::xyplot()
subset	See lattice::xyplot()
drop.unused.levels	See lattice::xyplot()
outer	Ignored.
allow.multiple	Ignored.

Value

An object of class "trellis". The update method can be used to update components of the object and the print method (usually called by default) will plot it on an appropriate plotting device.

Examples

bubbleplot(disp ~ hp * wt, groups = cyl, data = mtcars, auto.key = TRUE)
bubbleplot(disp ~ hp * mpg | factor(cyl), groups = gear, data = mtcars,
           auto.key = TRUE)
