Flatten Relations and Optionally Replace UUIDs

Source: R/fix_relations.R
fix_relations.Rd

Flattens the nested relations list of a resource into individual named vectors with a relation.-prefix (e.g. relation.isAbove), and optionally replaces UUIDs with human-readable identifiers from the index.

Usage

fix_relations(resource, replace_uids = TRUE, index = NULL, uidlist = NULL)

Arguments

resource

One element from an idaifield_resources list.

replace_uids

logical. Should UUIDs be replaced with identifiers from index? Default is TRUE.

index

A data.frame as returned by make_index() or get_field_index(). Required if replace_uids = TRUE.

uidlist

DEPRECATED

Value

The resource with its relations list removed and replaced by flat named vectors, one per relation type.
