cb_domain_from_data R Documentation
Extract domain from data
Description
Derives a domain (set of valid values) directly from the data object.
Uses dual dispatch on filter type and source type. Custom filter types
should implement S7 methods for this generic. The default method returns
'NULL' (no domain).
Usage
cb_domain_from_data(filter, source, ...)
Arguments
filter
S7 filter object.
source
Source object.
...
Additional arguments. Methods receive a 'data_object' (the data to
extract the domain from) here.
Value
Domain value appropriate for the filter type, or 'NULL'.
