Takes a DW state and returns the current active view
Arguments
- state
DW state from
DW_fetch_state()
Value
List containing the details of the active data view. The structure
of this list is the same as the structure of state$DW$views in the output of
DW_fetch_state().
Examples
library(formods)
# The example requires a formods DW state object
state = DW_test_mksession(session=list())$state
