Draw a random sample from a LogNormal distribution

Usage

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

Arguments

x

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

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

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).
