Serialize R objects to JSON, JavaScript Object Notation
Description
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 is 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.
