dot-resolve: Resolve downstream after selected changes

In teal.picks: Dataset and Variable Picker and Merge Module for 'teal' Applications

Resolve downstream after selected changes

Description

@description When select input at position i changes:

• All slots after position i in picks_resolved are reset to their unresolved (delayed) state, because later slots depend on earlier ones. Slots before and at position i are kept as-is. For example, changing variables (i=2) resets everything after it but keeps dataset (i=1) intact.

• The new selection replaces the old value at slot i.

• Resolve is called, which evaluates only the slots that are still in an unresolved state.

• The updated picks replace the current reactiveValue. Thanks to this design reactive values are triggered only once

Usage

.resolve(selected, slot_name, picks_resolved, old_picks, data)

Arguments

selected	(vector) rather character, or factor. numeric(2) for values() based on numeric column.
slot_name	(character(1)) one of c("datasets", "variables", "values")
picks_resolved	(reactiveVal)
old_picks	(picks)
data	(any asserted further in resolver)

Value

The result of changing the picks_resolved reactiveVal given as argument. It returns NULL if it does nothing.
