multhist: Plot a multiple histogram, as a barplot

Description Usage Arguments Value Note Author(s) See Also Examples

View source: R/multhist.R

Description

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

Usage

1
 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.
