Description

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

Usage

1
2
txtboxplot(..., range = 1.5, legend = NULL, xlab = NULL,
           width = round(options()$width * 0.8))

Arguments

...

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

Note

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.
