# cdf.Tukey: Evaluate the cumulative distribution function of a Tukey... In distributions3: Probability Distributions as S3 Objects

 cdf.Tukey R Documentation

## Evaluate the cumulative distribution function of a Tukey distribution

### Description

Evaluate the cumulative distribution function of a Tukey distribution

### Usage

```## S3 method for class 'Tukey'
cdf(d, x, drop = TRUE, elementwise = NULL, ...)
```

### Arguments

 `d` A `Tukey` distribution created by a call to `Tukey()`. `x` A vector of elements whose cumulative probabilities you would like to determine given the distribution `d`. `drop` logical. Should the result be simplified to a vector if possible? `elementwise` logical. Should each distribution in `d` be evaluated at all elements of `x` (`elementwise = FALSE`, yielding a matrix)? Or, if `d` and `x` have the same length, should the evaluation be done element by element (`elementwise = TRUE`, yielding a vector)? The default of `NULL` means that `elementwise = TRUE` is used if the lengths match and otherwise `elementwise = FALSE` is used. `...` Arguments to be passed to `ptukey`. Unevaluated arguments will generate a warning to catch mispellings or other possible errors.

### Value

In case of a single distribution object, either a numeric vector of length `probs` (if `drop = TRUE`, default) or a `matrix` with `length(x)` columns (if `drop = FALSE`). In case of a vectorized distribution object, a matrix with `length(x)` columns containing all possible combinations.

Other Tukey distribution: `quantile.Tukey()`

### Examples

```
set.seed(27)

X <- Tukey(4L, 16L, 2L)
X

cdf(X, 4)
quantile(X, 0.7)
```
