Units Attribute of a Vector

Sets or retrieves the "units" attribute of an object. For units.default replaces the builtin version, which only works for time series objects. If the variable is also given a label, subsetting (using [.labelled) will retain the "units" attribute. For a Surv object, units first looks for an overall "units" attribute, then it looks for units for the time2 variable then for time1.
