R Documentation

Get Wikidata property of an item as a character vector of the same length as input

Description

This function wraps tw_get_p(), but always sets only_first and preferred to TRUE in order to give back always a character vector.

Usage

tw_get_p1(
  id,
  p,
  latest_start_time = FALSE,
  language = tidywikidatar::tw_get_language(),
  id_df = NULL,
  cache = NULL,
  overwrite_cache = FALSE,
  cache_connection = NULL,
  disconnect_db = TRUE,
  wait = 0
)

Arguments

`id`	A character vector, must start with Q, e.g. "Q254" for Wolfgang Amadeus Mozart.
`p`	A character vector, a property. Must always start with the capital letter "P", e.g. "P31" for "instance of".
`latest_start_time`	Logical, defaults to FALSE. If TRUE, returns the property that has the most recent start time ("P580") as qualifier. If no such qualifier is found, then it is ignored.
`language`	Defaults to language set with `tw_set_language()`; if not set, "en". Use "all_available" to keep all languages. For available language values, see https://www.wikidata.org/wiki/Help:Wikimedia_language_codes/lists/all
`id_df`	Default to NULL. If given, it should be a dataframe typically generated with `tw_get_()`, and is used instead of calling Wikidata or replying on cache.
`cache`	Defaults to NULL. If given, it should be given either TRUE or FALSE. Typically set with `tw_enable_cache()` or `tw_disable_cache()`.
`overwrite_cache`	Logical, defaults to FALSE. If TRUE, it overwrites the table in the local sqlite database. Useful if the original Wikidata object has been updated.
`cache_connection`	Defaults to NULL. If NULL, and caching is enabled, `tidywikidatar` will use a local sqlite database. A custom connection to other databases can be given (see vignette `caching` for details).
`disconnect_db`	Defaults to TRUE. If FALSE, leaves the connection to cache open.
`wait`	In seconds, defaults to 0. Time to wait between queries to Wikidata. If data are cached locally, wait time is not applied. If you are running many queries systematically you may want to add some waiting time between queries.
