This function provides several styles of conditional plots with base
graphics.

Usage

cond.plot(x, y, z, Style="smoothscatter")

Arguments

x

This required argument accepts a numeric vector.

y

This argument accepts a numeric vector, and is only used with
some styles.

z

This required argument accepts a discrete vector.

Style

This argument specifies the style of plot, and accepts
"boxplot", "densover" (density overlay), "hist", "scatter", or
"smoothscatter".

Value

Conditional plots are returned.

Details

The cond.plot function provides simple conditional plots with
base graphics. All plot styles are conditional upon z. Up to
nine conditional plots are produced in a panel.

Plots include:

boxplot: y ~ x | z
densover: f(x | z)
hist: x | z
scatter: x, y | z
smoothscatter: x, y | z

The cond.plot function is not intended to try to compete with
some of the better graphics packages, but merely to provide simple
functionality.
