Pick the comparisons a defaults list asks for from those on offer

Source: R/stat_helper.R
default_stat_pairs.Rd

The Comparisons selector is repopulated from the data whenever its grouping columns change, so a stat.pairs default cannot simply be written into the UI. The modules instead select, from each fresh set of choices, the ones defaults$stat.pairs names. A pair matches in either orientation, so "Mid vs Entry" selects the "Entry vs Mid" choice.

Usage

default_stat_pairs(defaults, pair_strings)

Arguments

defaults

A named list of module defaults, or NULL.

pair_strings

Character vector of "A vs B" choices on offer, as from generate_pair_strings().

Value

The elements of pair_strings that defaults$stat.pairs names. When it names none, "", which is what the selector needs to show an empty selection (and means every pair is tested).

choices <- c("Entry vs Mid", "Entry vs Late", "Mid vs Late")
default_stat_pairs(list(stat.pairs = "Mid vs Entry"), choices)
#> [1] "Entry vs Mid"
default_stat_pairs(NULL, choices)
#> [1] ""
