histogram: Create a Histogram

In MichaelJMahometa/OnRampsR: Collection of functions for The University of Texas OnRamps Statistics course.

Description

Functional wrapper to hist() in graphics. Adds functionality (frequency table) and standard cut options (right=FALSE) to hist().

Usage

histogram(x, breaks = NULL, table = FALSE, right = FALSE,
  xlab = deparse(substitute(x)), title = NULL, ...)

Arguments

x	Variable to be plotted.
breaks	one of: a vector giving the breakpoints between histogram cells, a function to compute the vector of breakpoints, a function to compute the vector of breakpoints, a single number giving the number of cells for the histogram, a character string naming an algorithm to compute the number of cells, a function to compute the number of cells.
table	Logical: Should a frequency distribution table be produced?
right	Logical; if FALSE, the histogram cells are left-closed (right open) intervals.
xlab	Label of the x-axis. Default is the object name of x above.
title	Title (optional) of the chart.
...	Further arguments passed to or from other methods.

Examples

histogram(mtcars$hp)
histogram(mtcars$hp, breaks=seq(50, 350, by=25))
histogram(mtcars$hp, breaks=seq(50, 350, by=25), table=TRUE)
