rv (version 0.949)

integer.rv: Integer-valued Random Vectors

Description

Tests or coerces (numeric or logical-valued) random vector objects into integer-valued ones.

Usage

## S3 method for class 'rv':
is.integer(x)
  ## S3 method for class 'rv':
as.integer(x, \dots)

Arguments

x

an rv object

...

other arguments

Details

is.integer(x) returns TRUE if and only if each component of x is integer-valued.

as.integer.rv coerces an rv object into integer-valued one. In effect, the function as.integer is applied to all simulations.

Examples

x <- rvpois(lambda=1)   # some integer-valued random variable
  is.integer(x)           # FALSE, because by default x is 'double'!
  x <- as.integer(x)      # coerce to integer
  is.integer(x)           # TRUE
