New Data Wrangling View — DW_new

Appends a new empty data wrangling view to the DW state object and makes this new view the active view.

Usage

DW_new_view(state)

Arguments

state: DW state from DW_fetch_state()

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.

Examples

library(formods)
# The example requires a formods DW state object
state  = DW_test_mksession()$state
