Determine quantiles of a Tukey distribution

Determine quantiles of a Tukey distribution

Usage

# S3 method for Tukey
quantile(x, probs, drop = TRUE, elementwise = NULL, ...)

Arguments

x

A vector of elements whose cumulative probabilities you would like to determine given the distribution d.

probs

A vector of probabilities.

drop

logical. Should the result be simplified to a vector if possible?

elementwise

logical. Should each distribution in x be evaluated at all elements of probs (elementwise = FALSE, yielding a matrix)? Or, if x and probs 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 qtukey. 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(probs) columns (if drop = FALSE). In case of a vectorized distribution object, a matrix with length(probs) columns containing all possible combinations.

Examples

set.seed(27)

X <- Tukey(4L, 16L, 2L)
X
#> [1] "Tukey distribution (nmeans = 4, df = 16, nranges = 2)"

cdf(X, 4)
#> [1] 0.9009192
quantile(X, 0.7)
#> [1] 3.075961
