Draw a random sample from a Beta distribution

Usage

# S3 method for class 'Beta'
random(x, n = 1L, drop = TRUE, ...)

Arguments

x: A Beta object created by a call to Beta().
n: The number of samples to draw. Defaults to 1L.
drop: logical. Should the result be simplified to a vector if possible?
...: Unused. Unevaluated arguments will generate a warning to catch mispellings or other possible errors.

Value

Values in [0, 1]. In case of a single distribution object or n = 1, either a numeric vector of length n (if drop = TRUE, default) or a matrix with n columns (if drop = FALSE).
