numeric.rv: Numeric Random Vectors

Description

is.numeric(x) returns TRUE if and only if all components of an rv object are numeric.

Usage

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

Arguments

an rv object

Details

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

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

Random factors are not numeric; mixtures are.

Examples

Run this code

x <- as.logical(rvbern(1,0.5)) # Bernoulli rv
  is.numeric(x)           # FALSE
  x <- as.numeric(x)      # coerce to numeric; all TRUEs become ones, FALSEs zeros
  is.numeric(x)           # TRUE
