Get image from Wikimedia Commons

Please consult the relevant documentation for reusing content outside Wikimedia: https://commons.wikimedia.org/wiki/Commons:Reusing_content_outside_Wikimedia/technical

Usage

tw_get_image(
  id,
  format = "filename",
  width = NULL,
  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 of length 1, must start with Q, e.g. "Q254" for Wolfgang Amadeus Mozart.

format

A character vector, defaults to 'filename'. If set to 'commons', outputs the link to the Wikimedia Commons page. If set to "embed", outputs a link that can be used to embed.

width

A numeric value, defaults to NULL, relevant only if format is set to 'embed'. If not given, defaults to full resolution image.

language

Needed for caching, 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 using SQLite cache. Ignored when id is of length more than one.

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.

Value

A data frame of two columns, id and image, corresponding to reference to the image in the requested format.

Examples

tw_get_image("Q180099",
  format = "filename"
)
#> # A tibble: 1 × 2
#>   id      image                        
#>   <chr>   <chr>                        
#> 1 Q180099 Margaret Mead (1901-1978).jpg

if (interactive()) {

  )

  tw_get_image("Q180099",
    format = "embed",
    width = 300
  )
