## Formula Notation for Scatterplot Matrices

### Description

Produce a matrix of scatterplots using formula notation.

### Usage

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

### Arguments

`formula` | a formula, such as `y ~ x`.
`data` | a data.frame (or list) from which the variables in `formula` should be taken.
`...` | arguments to the default pairs method and graphical parameters may also be passed as arguments, see `par`.
`subset` | an optional vector specifying a subset of observations to be used for plotting.

### 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`.

### See Also

`pairs.default`

### Examples

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