This is a package that allows conversion to and from
data in Javascript object notation (JSON) format.
This allows R objects to be inserted into Javascript/ECMAScript/ActionScript code
and allows R programmers to read and convert JSON content to R objects.
This is an alternative to rjson package. That version was too slow for converting large R objects to JSON
and is not extensible, but a very useful prototype.  It is fast for parsing.
This package uses methods, vectorized operations and C code and callbacks to R functions
for deserializing JSON objects to R.
Verison 0.4 of this package uses a new native parser, implements the transformation code
in C and allocates memory efficiently (rather than concatenating because of event driven parsing).
The result is a significantly faster parsing of large JSON documents.

This is an alternative to rjson package. Originally, that was too slow for converting large R objects to JSON
and was not extensible.  rjson's performance is now similar to this package, and perhaps slightly faster in some cases.
This package uses methods and is readily extensible by defining methods for different classes,
vectorized operations, and C code and callbacks to R functions for deserializing JSON objects to R.
The two packages intentionally share the same basic interface. This package (RJSONIO) has many additional
options to allow customizing the generation and processing of JSON content.
This package uses libjson rather than implementing yet another JSON parser. The aim is to support
other general projects by building on their work, providing feedback and benefit from their ongoing development.
