reap: Call a function continuing the random number stream.

In harvestr: A Parallel Simulation Framework

Description

The reap function is the central function to harvest. It takes an object, x, extracts the previous seed, ie. state of the random number generator, sets the seed, and continues any evaluation. This creates a continuous random number stream, that is completly reproducible.

Usage

reap(x, fun, ..., hash = digest(list(x, fun, ..., source = "harvestr::reap"),
  "md5"), cache = getOption("harvestr.use.cache", defaults$cache()),
  cache.dir = getOption("harvestr.cache.dir", defaults$cache.dir()),
  time = getOption("harvestr.time", defaults$time()),
  use.try = getOption("harvestr.use.try", !interactive()))

Arguments

x	an object
fun	a function to call on object
...	passed onto function
hash	hash of the list to retrieve the cache from.
cache	use cache, see Caching in harvestr
cache.dir	directory for the cache.
time	should results be timed?
use.try	Should the call be wrapped in try?

Details

The function calling works the same as the apply family of functions.
