IRW Collection Membership

The long membership table: one row per (table, collection) pair, with the basis on which that membership was decided — a rule expression, or a curator. Use this to ask the inverse question: what collections is a given table in?

Usage

irw_collection_members(tables = NULL, collection = NULL)

Arguments

tables

Optional character vector. Restrict to these table names.

collection

Optional character vector. Restrict to these collections.

Value

A tibble with columns table, collection, basis.

Basis in the exact-instrument collections

In the exact-instrument collections (phq9, gad7, rses, cesd, dass21, panas, tipi, pcl5, gse, erq, mspss, sd3), basis starts with how the table was identified as that instrument:

wording

The study's own item text matches the instrument. Identity is observed.

supplied

IRW identified the instrument and supplied its canonical wording, so a wording match only confirms that identification. Identity is asserted.

name

There is no usable English item text; only the table's metadata names the instrument.

A note may follow after "; ": "supplied; subscale: anxiety (7/21)" for a table holding one whole subscale, "name; partial: 18/20 items" for one holding most of the scale. For the strictly verified set, keep rows whose basis starts with "wording", not rows equal to it.

Examples

if (FALSE) { # irw_has_credentials() || nzchar(Sys.getenv("IRW_RUN_EXAMPLES"))
# \donttest{
irw_collection_members(tables = "frac20")
irw_collection_members(collection = "q_matrix")

# PHQ-9 tables whose own item text was checked against the instrument
m <- irw_collection_members(collection = "phq9")
m[startsWith(m$basis, "wording"), ]
# }
