rvmapply
is the rv-compatible version of mapply
. It
repeats the function FUN
for each joint draw of the random (or
constant) arguments, while allowing vectorizing.

rvmapply
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.
The dimensions of each joint draw are preserved. For an example, see
solve
, that returns the distribution of the inverse of a
random matrix.
Usually used in functions that implement an 'rv'-compatible routine.
For an example of a function that uses SAMPLESIZE
,
abline
.
Depends on FUN
; a random vector or array if FUN
is
numeric.
If the function (FUN
) has an argument “FUN
", it must be
specified within the list supplied to MoreArgs
.
