Examples
library(formods)
# The example requires a formods DW state object
state = DW_test_mksession(session=list())$state
state[["DW"]][["ui"]][["select_dw_element"]] = "filter"
state[["DW"]][["ui"]][["select_fds_filter_column"]] = "EVID"
state[["DW"]][["ui"]][["select_fds_filter_operator"]] = "=="
state[["DW"]][["ui"]][["fds_filter_rhs"]] = 0
# This builds the data wrangling statement based on
# elemets scraped from the UI
dwb_res = dwrs_builder(state)
# Here we evaluate the resulting command:
dwee_res = dw_eval_element(state, dwb_res[["cmd"]])
# Next we add this wrangling element to the state
state = DW_add_wrangling_element(state, dwb_res, dwee_res)
# This creates a new data view and makes it active
state = DW_new_view(state)
# Here we can pluck out that data view from the state
current_view = DW_fetch_current_view(state)
# This will update the key in this view
current_view[["key"]] = "My new view"
# And this will place it back into the state
state = DW_set_current_view(state, current_view)
