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)
