rv (version 0.949)

mapply.rv: Apply a function to multiple random vector arguments

Description

mapply.rv is a rv-compatible version of mapply. It repeats the function FUN for each joint draw of the random (or constant) arguments.

Usage

mapply.rv(FUN, ..., MoreArgs=NULL, USE.NAMES=TRUE, SAMPLESIZE=NULL)

Arguments

FUN

the function to apply to the simulations of X.

MoreArgs

Other args passed to FUN `as is'

USE.NAMES

logical; see mapply for details

SAMPLESIZE

number of simulations to process. This should be not specified whenever the function is numeric.

...

further arguments to FUN, possibly random vectors or array.

Value

• Depends on FUN; a random vector or array if FUN is numeric.

Details

mapply.rv applies a given function to each simulation (vector or array) of the given random vectors, returning a the results as a random vector or array.

Usually used in functions that implement an 'rv'-compatible routine.

For an example of a function that uses SAMPLESIZE, abline.
