Description

These function returns an iterators that return random numbers of various distributions. Each one is a wrapper around a standard R function.

Usage

irnorm(..., count)
irunif(..., count)
irbinom(..., count)
irnbinom(..., count)
irpois(..., count)

Arguments

count

number of times that the iterator will fire. If not specified, it will fire values forever.

...

arguments to pass to the underlying rnorm function.

Value

• An iterator that is a wrapper around the corresponding random number generator function.

Examples

# create an iterator that returns three random numbers
  it <- irnorm(1, count=3)
  nextElem(it)
  nextElem(it)
  nextElem(it)
  try(nextElem(it))  # expect a StopIteration exception
