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 NAs.

...

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)
