Draw a random sample from an F distribution
Usage
# S3 method for class 'FisherF'
random(x, n = 1L, drop = TRUE, ...)
Arguments
- x
A
FisherF
object created by a call toFisherF()
.- 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
).
Examples
set.seed(27)
X <- FisherF(5, 10, 0.2)
