A numeric variable can be discrete (support is then the set of all possible values, either integer or double; integers of length 2 are interpreted as all integers inbetween) or continuous (support is a double of length 2 giving the support of the data).
If a continuous variable is bounded, bounds
defines the
corresponding interval.
An object of class numeric\_var
inheriting from var
with
corresponding methods.

numeric_var("time", "survival time", "days", support = 0:365)
numeric_var("time", "survival time", "days", support = c(0.0, 365),
bounds = c(0, Inf))
