R: Plot a Histogram

Hist	R Documentation

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 returns NULL, and is called for its side effect — plotting a histogram.
