Usage

wiki_diff(con, revisions, properties = c("ids", "flags", "timestamp", "user",
  "userid", "size", "sha1", "contentmodel", "comment", "parsedcomment", "tags",

Warnings

MediaWiki's API is deliberately designed to restrict users' ability to make computing-intense requests - such as diff computation. As a result, the API only allows requests for one uncached diff in each request. If you ask for multiple diffs, some uncached and some cached, you will be provided with the cached diffs, one of the uncached diffs, and a warning.

If you're going to be asking for a lot of diffs, some of which may not be cached, it may be more sensible to retrieve the revisions themselves using wiki_revision and compute the diffs yourself.
