rv (version 0.949)

logical.rv: Logical Random vectors

Description

is.logical(x) returns TRUE for each component that contains an logical-valued vector, otherwise FALSE is given.

Usage

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

Arguments

x

an rv object

Details

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

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

Examples

x <- rvbern(prob=0.5)   # some 0/1 valued random variable
  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
