tw_get_p1 {tidywikidatar} | 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 |
id_df |
Default to NULL. If given, it should be a dataframe typically generated with |
cache |
Defaults to NULL. If given, it should be given either TRUE or FALSE. Typically set with |
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, |
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. |
Value
A character vector of the same length as the input.
Examples
tw_get_p1(id = "Q180099", "P26")
