multhist: Plot a multiple histogram, as a barplot

In plotrix: Various Plotting Functions

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.

Note

The 'inside' argument to barplot (which is not currently implemented in barplot anyway) is deleted from the argument list. The default value of NULL for ‘⁠freq⁠’ is for consistency with ‘⁠hist⁠’ but is equivalent to TRUE.
