discrete.histogram {arm} | R Documentation

## 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)
