Plot Method for Data Frames

Description:

     'plot.data.frame', a method for the 'plot' generic. It is designed
     for a quick look at numeric data frames.

Usage:

     ## S3 method for class 'data.frame':
     plot(x, ...)

Arguments:

       x: object of class 'data.frame'.

     ...: further arguments to 'stripchart', 'plot.default' or 'pairs'.

Details:

     This is intended for data frames with _numeric_ columns. For more
     than two columns it first calls 'data.matrix' to convert the data
     frame to a numeric matrix and then calls 'pairs' to produce a
     scatterplot matrix).  This can fail and may well be inappropriate:
     for example numerical conversion of dates will lose their special
     meaning and a warning will be given.

     For a two-column data frame it plots the second column against the
     first by the most appropriate method for the first column.

     For a single numeric column it uses 'stripchart', and for other
     single-column data frames tries to find a plot method for the
     single column.
