## 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)
```
