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")
