Formula Notation for Scatterplot Matrices

Description

Produce a matrix of scatterplots using formula notation.

Usage

pairs.formula(formula, data = NULL, subset, na.action, ...)

Arguments

`formula`	a formula, such as `y ~ x`.
`data`	a data.frame (or list) from which the variables in `formula` should be taken.
`subset`	an optional vector specifying a subset of observations to be used in the fitting process.
`na.action`	a function which indicates what should happen when the data contain `NA`s.
`...`	graphical parameters may also be passed as arguments, see `par`.

Details

This is a method of the generic function pairs. It operates by setting up the data from the formula specification, and then calling pairs.default.

Examples

data(swiss)
pairs(~ Fertility + Education + Catholic,
      data = swiss, subset = Education < 20)
