add_entity_pattern: Add a custom entity pattern

Description

This function allows users to extend the default entity patterns with a custom entry.

Usage

add_entity_pattern(
  entity_id,
  entity_name,
  entity_type,
  aliases = NULL,
  entity_regex = NULL
)

Value

NULL. As a side effect of the function, the custom pattern is stored in an internal tibble for the current session.

Arguments

entity_id

A unique identifier for the entity.

entity_name

The standard (canonical) name of the entity.

entity_type

A character string describing the type of entity ("economy", "organization", "aggregate", or "other").

aliases

An optional character vector of alternative names identifying the entity. If provided, these are automatically combined (using the pipe operator, "|") with entity_name and entity_id to construct a regular expression pattern.

entity_regex

An optional custom regular expression pattern. If supplied, it overrides the regex automatically constructed from aliases.

Details

Custom entity patterns can be added at the top of a script (or interactively) and will be appended to the built-in patterns when using list_entity_patterns(). This makes it possible for users to register alternative names (aliases) for entities that might appear in their economic datasets.

The custom entity patterns are kept separately and are appended to the default patterns when retrieving the entity_patterns via list_entity_patterns(). The custom patterns will only persist for the length of the R session.

Examples

add_entity_pattern(
  "ASN",
  "Association of Southeast Asian Nations",
  "economy",
  aliases = c("ASEAN")
)
patterns <- list_entity_patterns()
print(patterns[patterns$entity_id == "ASN", ])
