R: Plot Method for Data Frames

plot.data.frame {graphics} | R Documentation

## 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.
