R: Text based boxplot

R Documentation

Text based boxplot

Produces rudimentary ascii boxplots. The boxplot statistics are produced using the boxplot.stats function.

txtboxplot(..., range = 1.5, legend = NULL, xlab = NULL,
           width = round(options()$width * 0.8))

`...`	Numeric vectors for which a boxplot should be produced
`range`	This determines how far the plot whiskers extend out from the box. See `boxplot.stats` and the `coef` function for details.
`legend`	Logical determining whether a legend should be drawn. If `legend` is NULL there will be a legend drawn in case there is more than one boxplot.
`xlab`	label for x-axis of boxplot, if NULL no x-label will be plotted
`width`	Width of the plot

Due to rounding to a relatively crude grid results can only be approximate. E.g. the equally spaced axis ticks may be non-equally spaced in the plot.
