pages_in_category: Retrieves a list of category members.

Description

wiki_catpages retrieves a list of pages, subcategories, files or all of the above in a specified category (or series of specified categories)

Usage

pages_in_category(
  language = NULL,
  project = NULL,
  domain = NULL,
  categories,
  properties = c("title", "ids", "sortkey", "sortkeyprefix", "type", "timestamp"),
  type = c("page", "subcat", "file"),
  clean_response = FALSE,
  limit = 50,
  ...
)

Arguments

language

The language code of the project you wish to query, if appropriate.

project

The project you wish to query ("wikiquote"), if appropriate. Should be provided in conjunction with language.

domain

as an alternative to a language and project combination, you can also provide a domain ("rationalwiki.org") to the URL constructor, allowing for the querying of non-Wikimedia MediaWiki instances.

categories

The names of the categories you want to gather information for.

properties

The properties you want to gather for each member of the category. Options are "title" (the name of the member, including namespace), "id" (the unique numeric identifier of the member), "sortkey" (the hexadecimal key used to sort that member within the category), "sortkeyprefix" (the human-readable sort key), "type" (whether the member is a page, a subcategory or a file) and "timestamp" (when the member was added to the category)

type

The type of member you're interested in returning; options are any permutation of "page" (pages), "subcat" (subcategories) and "file" (files).

clean_response

whether to do some basic sanitising of the resulting data structure. Set to FALSE by default.

limit

The maximum number of members to retrieve for each category. Set to 50 by default.

...

further arguments to pass to httr's GET().

warnings

Because of the way MediaWiki stores this data, both "the category you asked for doesn't exist" and "the category you asked for exists, but has no members" return in the same way.
