as.logical.rv: Logical Random vectors

In rv: Simulation-Based Random Variable Objects

Logical Random vectors

Description

Coerces a random variable to a logical-valued one (Bernoulli r.v.)

Usage

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

Arguments

x	an rv object
...	Further arguments passed on

Details

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

Note

is.logical(x) returns TRUE if and only if each component of x is logical-valued (i.e. TRUE/FALSE).

Examples

  x <- rvbern(prob=0.5)   # some 0/1 valued random variable
  print(x)
  is.logical(x)           # FALSE, because by default x is 'double'
  x <- as.logical(x)      # coerce to logical; all zeros become FALSE, ones become TRUE
  is.logical(x)           # TRUE
  print(x)                # Shows the expectations and not the quantiles
