locale

If not NULL, will set the locale for the search. As of 03/06/11 only ja is effective, as per the Twitter API

geocode

If not NULL, returns tweets by users located within a given radius of the given latitude/longitude. See Details below for more information

sinceID

resultType

If not NULL, returns filtered tweets as per value. See details for allowed values.

retryOnRateLimit

If non-zero the search command will block retry up to X times if the rate limit is experienced. This might lead to a much longer run time but the task will eventually complete if the retry count is high enough

Details

These commands will return any authorized tweets which match the search criteria. Note that there are pagination restrictions as well as other limits on what can be searched, so it is always possible to not retrieve as many tweets as was requested with the n argument. Authorized tweets are public tweets as well as those protected tweets that are available to the user after authenticating via registerTwitterOAuth.

The searchString is always required. Terms can contain spaces, and multiple terms should be separated with "+".

For the geocode argument, the values are given in the format latitude,longitude,radius, where the radius can have either mi (miles) or km (kilometers) as a unit. For example geocode='37.781157,-122.39720,1mi'.

For the sinceID argument, if the requested ID value is older than the oldest available tweets, the API will return tweets starting from the oldest ID available.

For the maxID argument, tweets upto this ID value will be returned starting from the oldest ID available. Useful for paging.

The resultType argument specifies the type of search results received in API response. Default is mixed. Allowed values are mixed (includes popular + real time results), recent (returns the most recent results) and popular (returns only the most popular results).

The Rtweets function is a wrapper around searchTwitter which hardcodes in a search for #rstats.
