as.integer.rv: Integer Random vectors

In rv: Simulation-Based Random Variable Objects

Integer Random vectors

Description

Coerces a random variable to an integer-valued (discrete) one

Usage

## S3 method for class 'rv'
as.integer(x, ...)

Arguments

x	an rv object
...	Further arguments passed on

Details

In effect, the function as.integer is applied to all simulations.

Note

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

Examples

  x <- rvpois(lambda=3)   # some integer-valued random variable
  print(x)
  is.integer(x)           # FALSE, because by default x is 'double'!
  x <- as.integer(x)      # coerce to integer
  is.integer(x)           # TRUE
  print(x)                # Shows also the 'min' and 'max' columns
