multhist {plotrix}R Documentation

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

the breaks and the values for the histograms.

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.
