Hist: Plot a Histogram

In RcmdrMisc: R Commander Miscellaneous Functions

Plot a Histogram

Description

Plot a Histogram

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 (or character or logical variable) 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.

Details

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.

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.
