sims: Retrieve the Simulations of Random Vectors

In jsta/rv: Simulation-Based Random Variable Objects

Description

Returns the simulation matrix for the random variable object x.

Usage

sims(x, ...)

## S3 method for class 'rvsummary'
sims(x, dimensions = FALSE, ...)

## S3 method for class 'rv'
sims(x, dimensions = FALSE, n.sims = getnsims(), ...)

Arguments

x	a random variable object
...	arguments passed on
dimensions	logical, try to preserve the dimensions of x
n.sims	(optional) number of simulations

Details

sims returns the matrix of simulations for a given random variable object x.

The first index of the matrix indicates the number of the simulation draw ("simulations are in rows").

Examples

  setnsims(n.sims=2500)
  x <- rvnorm(24)
  dim(x) <- c(2,3,4)
  dim(sims(x))                  # 2500x24
  dim(sims(x, dimensions=TRUE)) # 2500x2x3x4
