# DiscreteUniform: Discrete uniform distribution In extraDistr: Additional Univariate and Multivariate Distributions

## Description

Probability mass function, distribution function, quantile function and random generation for the discrete uniform distribution.

## Usage

 ```1 2 3 4 5 6 7``` ```ddunif(x, min, max, log = FALSE) pdunif(q, min, max, lower.tail = TRUE, log.p = FALSE) qdunif(p, min, max, lower.tail = TRUE, log.p = FALSE) rdunif(n, min, max) ```

## Arguments

 `x, q` vector of quantiles. `min, max` lower and upper limits of the distribution. Must be finite. `log, log.p` logical; if TRUE, probabilities p are given as log(p). `lower.tail` logical; if TRUE (default), probabilities are P[X ≤ x] otherwise, P[X > x]. `p` vector of probabilities. `n` number of observations. If `length(n) > 1`, the length is taken to be the number required.

## Details

If `min == max`, then discrete uniform distribution is a degenerate distribution.

## Examples

 ```1 2 3 4 5 6 7 8``` ```x <- rdunif(1e5, 1, 10) xx <- -1:11 plot(prop.table(table(x)), type = "h") lines(xx, ddunif(xx, 1, 10), col = "red") hist(pdunif(x, 1, 10)) xx <- seq(-1, 11, by = 0.01) plot(ecdf(x)) lines(xx, pdunif(xx, 1, 10), col = "red") ```
