Derives a domain (set of valid values) from previously computed filter
statistics. Custom filter types should implement an S7 method for this
generic. The default method returns `NULL` (no domain).
Usage
cb_domain_from_stats(filter, ...)
Arguments
- filter
S7 filter object.
- ...
Additional arguments. Methods receive `stats`, the list of stored
statistics for the filter.
Value
Domain value appropriate for the filter type, or `NULL`.
