Histogram for Discrete Distributions

Description

Creates a prettier histogram for discrete distributions

Usage

discrete.histogram (x, prob, prob2=NULL, prob3=NULL,
    xlab="x", xaxs.label=NULL, yaxs.label=NULL, bar.width=NULL,
    freq=FALSE, prob.col="blue", prob2.col="red", prob3.col="gray", ...)

Arguments

`x`	The vector of x's
`prob`	The probabilities for the x's
`prob2`	A second vector of probabilities of the x's
`prob3`	A third vector of probabilities of the x's
`xlab`	Label for the x axis
`xaxs.label`	Label for the x's
`yaxs.label`	Label for the y axis
`bar.width`	Width of the bars
`freq`	If TRUE, shows a frequency histogram as opposed to probability.
`prob.col`	The color of the first set of histogram bars.
`prob2.col`	The color of the second set of histogram bars.
`prob3.col`	The color of the third set of histogram bars.
`...`	Additional arguments passed to function `plot`

Details

This function displays a histogram for discrete probability distributions.

Examples

a <- c(3,4,0,0,5,1,1,1,1,0)
discrete.histogram (a)

x <- c(0,1,3,4,5)
p <- c(.3,.4,.1,.1,.1)
discrete.histogram (x,p)

x <- c(0,1,3,4,5)
y <- c(3,4,1,1,1)
discrete.histogram (x,y)
