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.

Examples

plot(OrchardSprays[1], method="jitter")
plot(OrchardSprays[c(4,1)])
plot(OrchardSprays)
