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

 ```1 2 3``` ```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

 ``` 1 2 3 4 5 6 7 8 9 10``` ```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) ```
