rv (version 1.0)

Math.rv: Mathematical functions and Operators for rv Objects

Description

Mathematical functions and operators adapted to work with random variable (rv) objects.

Usage

## S3 method for class 'rv':
Math(x, ...)
  ## S3 method for class 'rv':
Ops(e1, e2)

Arguments

x

object

e1

object

e2

object

...

further arguments passed to or from other methods

Details

The operator method preserves the names of the longer vector (or those of the first if the lengths match).
