quantile.Categorical: Determine quantiles of a Categorical discrete distribution

In distributions3: Probability Distributions as S3 Objects

Determine quantiles of a Categorical discrete distribution

Description

quantile() is the inverse of cdf().

Usage

## S3 method for class 'Categorical'
quantile(x, probs, ...)

Arguments

x	A Categorical object created by a call to Categorical().
probs	A vector of probabilities.
...	Unused. Unevaluated arguments will generate a warning to catch mispellings or other possible errors.

Value

A vector of quantiles, one for each element of probs.

Examples

set.seed(27)

X <- Categorical(1:3, p = c(0.4, 0.1, 0.5))
X

Y <- Categorical(LETTERS[1:4])
Y

random(X, 10)
random(Y, 10)

pdf(X, 1)
log_pdf(X, 1)

cdf(X, 1)
quantile(X, 0.5)

# cdfs are only defined for numeric sample spaces. this errors!
# cdf(Y, "a")

# same for quantiles. this also errors!
# quantile(Y, 0.7)
