quantile.Categorical: Determine quantiles of a Categorical discrete distribution

Description

quantile() is the inverse of cdf().

Usage

# S3 method for Categorical
quantile(d, p, ...)

Arguments

d

A Categorical object created by a call to Categorical().

p

A vector of probabilites.

...

Unused. Unevaluated arguments will generate a warning to catch mispellings or other possible errors.

Value

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

Examples

# NOT RUN {
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)
# }
# NOT RUN {
# cdfs are only defined for numeric sample spaces. this errors!
cdf(Y, "a")

# same for quantiles. this also errors!
quantile(Y, 0.7)
# }
# NOT RUN {
# }
