is.numeric(x) returns TRUE if and only if all components
of an rv object are numeric.
## S3 method for class 'rv': is.numeric(x) ## S3 method for class 'rv': as.numeric(x, ...) ## S3 method for class 'rvfactor': is.numeric(x) ## S3 method for class 'rvmixed': is.numeric(x)

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.
