The picker's defaults: which life stage and which denominator open a taxon (D8 rule 4)

Given the per-dataset x life-stage coverage of a taxon — one row per (dataset_key, life_stage) with n rows, n_10m2 rows that can be expressed per 10 m2 and n_1000m3 per 1000 m3 — the default stage is the one with the most rows carrying effort (tie: most rows), and the default denominator is the one that covers the most datasets with effort for that stage — never largest-n; per_10m2 on a tie; raw only when nothing carries effort. Eggs and larvae are never merged. The explorer's state.ts implements the same two functions.

Usage

cc_default_stage(picker)

cc_default_denominator(picker, stage)

Arguments

picker

data frame with dataset_key, life_stage, n, n_10m2, n_1000m3.

stage

a life stage in picker$life_stage (NA for rows without one).

Value

cc_default_stage(): a life stage (or NA); cc_default_denominator(): one of "per_10m2", "per_1000m3", "raw".

Examples

p <- data.frame(dataset_key = c("swfsc_ichthyo", "swfsc_ichthyo", "swfsc_cufes"),
                life_stage = c("larva", "egg", "egg"), n = c(7420, 5906, 49572),
                n_10m2 = c(6158, 4907, 0), n_1000m3 = c(7420, 5906, 0))
cc_default_stage(p)
#> [1] "larva"
cc_default_denominator(p, "larva")
#> [1] "per_10m2"
