multhist: Plot a multiple histogram, as a barplot

Description

Given a list, plots a side-by-side barplot containing the histograms of the elements

Usage

multhist(x,beside=TRUE,freq=NULL,probability=!freq,plot.it=TRUE,...)

Arguments

x

a list of numeric vectors

beside

plot histogram bars for groups side-by-side?

freq

logical; if 'TRUE', the histogram graphic is a representation of frequencies, the 'counts' component of the result; if 'FALSE', probability densities, component 'density', are plotted (so that the histogram has a total area of one). Defaults to 'TRUE' if 'probability' is not specified (does not consider equidistant breaks as in hist)

probability

an alias for '!freq', for S compatibility

plot.it

Whether or not to display the histogram.

...

additional arguments to hist or barplot

Value

A list including the return value for the first call to hist (itself a list) and the values for the bar heights.
