Описание тега rjsonio
RJSONIO is an r package that allows conversion to and from data in Javascript object notation ( json) format. This allows R objects to be inserted into javascript/ actionscript code and allows R programmers to read and convert JSON content to R objects. It is an alternative to the rjson package. The RJSONIO package uses methods, vectorized operations and c code and callbacks to R functions for deserializing JSON objects to R. It allows fast parsing of large JSON documents.
The primary functions in the package are
fromJSONtoJSONasJSVars
The package is extensible, allowing others to define S4 methods for toJSON for different R classes/types. Similarly, the fromJSON function allows the caller to specify a different callback handler which is invoked each time an element (e.g. number, string, key, start or end of an array or object) is found in the JSON content.
