yield,Streamer-method

A <code>Stream</code>, <code>Producer</code>, or <code>Consumer</code> object.

<code>yield</code> invoked on a stream yields one chunk of data or, if the
 stream is complete, a length zero element of the data. Successive
 invocations of <code>yield</code> produce successive chunks of data.

Large data files can be difficult to work with in R,
where data generally resides in memory. This package encourages a
style of programming where data is 'streamed' from disk into R via
a `producer' and through a series of `consumers' that, typically
reduce the original data to a manageable size. The package
provides useful Producer and Consumer stream components for
operations such as data input, sampling, indexing, and
transformation; see package?Streamer for details.
