Hist: Plot a Histogram

Description

This function is a wrapper for the hist function in the base package, permitting percentage scaling of the vertical axis in addition to frequency and density scaling.

Usage

Hist(x, groups, scale=c("frequency", "percent", "density"), xlab=deparse(substitute(x)), 
    ylab=scale, main="", breaks = "Sturges", ...)

Arguments

x

a vector of values for which a histogram is to be plotted.

groups

a factor to create histograms by group with common horizontal and vertical scales.

scale

the scaling of the vertical axis: "frequency" (the default), "percent", or "density".

xlab

x-axis label, defaults to name of variable.

ylab

y-axis label, defaults to value of scale.

main

main title for graph, defaults to empty.

breaks

see the breaks argument for hist.

…

arguments to be passed to hist.

Value

This function is primarily called for its side effect --- plotting a histogram or histograms --- but it also invisibly returns an object of class hist or a list of hist objects.
