tinyjs - Lightweight Embedded JavaScript Engine (a wrapper for TinyJS)

An R interface to the 'TinyJS' — https://github.com/gfwilliams/tiny-js — JavaScript engine; a more lightweight alternative to 'V8' with no external dependencies.

The following functions are implemented:

• source_js : source a javascript file
• eval_js : evaluate javascript strings
• js_get : get javascript objects

The following data sets are included:

• system.file("js/test001.js", package="tinyjs")
• system.file("js/test002.js", package="tinyjs")
• system.file("js/test003.js", package="tinyjs")
• system.file("js/test004.js", package="tinyjs")
• system.file("js/test005.js", package="tinyjs")
• system.file("js/test006.js", package="tinyjs")
• system.file("js/test007.js", package="tinyjs")
