Appends a new empty data wrangling view to the DW state object and makes this new view the active view.
Arguments
- state
DW state from
DW_fetch_state()- session
Shiny session variable
Value
DW state object containing a new data view and that view set as the
current active view. See the help for DW_fetch_state() for view
format.
