discrete.histogram: Histogram for Discrete Distributions

In arm: Data Analysis Using Regression and Multilevel/Hierarchical Models

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)
