Creates or coerces rv objects of type "numeric".
# S3 method for rv
is.numeric(x)
# S3 method for rv
as.numeric(x, ...)
# S3 method for rvfactor
as.numeric(x, ...)an rv object to be coerced or tested.
further arguments passed to or from other methods.
is.numeric(x) returns TRUE if and only if each
component of x is numeric-valued.
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 (just as non-random factors aren't).

x <- as.numeric(x) # coerce to numeric; all TRUEs become ones, FALSEs zeros
