Introduction
-----------------------------------------------------------------------------
R-Node is a web front-end to the statistical analysis package R.
Using this front-end, you can from any web browser connect to an R instance
running on a remote (or local) server, and interact with it, sending commands
and receiving the responses.
In particular, graphing commands such as plot() and hist() will execute in
the browser, drawing the graph as an SVG image.

Major Software Utilised
-----------------------------------------------------------------------------
This software would not be where it is today without a number of key
technology projects that it uses. These are, in no particular order:
* Functional Javascript
Support for functional programming idioms when writing Javascript. -
see http://osteele.com/sources/javascript/functional/
* ExtJS
ExtJS provides the windowing library widgets used for the interface.
* Node.JS - http://nodejs.org/
An events based I/O library and execution environment for V8 Javascript
(http://code.google.com/p/v8/, the Google Chrome javascript engine).
This provides an exceedingly easy environment to develop the server
componentry in for R-Node.
* Protovis - http://vis.stanford.edu/protovis/
Protovis provides an excellent graphing API, allowing the graphical
commands of R to be effectively implemented in the browser.
* Rserve - http://www.rforge.net/Rserve/doc.html
This is a binary server that allows communication over tcp/ip with a
running R instance. It is used by the R-Node server componentry to
communicate with R.
* R - http://www.r-project.org/
* SHJS http://shjs.sourceforge.net/
Syntax highlighting for R code, used in the client application.
Each of these projects has their own licensing, as mentioned below. The
R-Node code itself is covered by a number of licenses due to the use of
these projects as libraries and in some cases as code embedded within
R-Node.
Licenses
-----------------------------------------------------------------------------
* Functional Javascript
Licenced under the MIT license.

* ExtJS
ExtJS 3 is licensed under the GNU GPL license v3 license, as mentioned here:

* Node.JS
BSD license. R-Node uses the Node.JS software to execute its server
side component, but does not alter the source at all. All Node.JS
source can be retreived from http://nodejs.org/.
* Protovis
BSD license. R-Node uses protovis but (currently) does not alter the
source code. The standard minified protovis library is included
for installation simplicity. All source can be retrieved from
http://gitorious.com/protovis.
* Rserve
R-Node connects to Rserve over TCP/IP, and assumes that Rserver is
installed and running already on the system. Some Rserve example
code has been used in creating the server library for connecting
to Rserve (see server/src/include), and this is
This code is distributed originally under the GNU LGPL, and continues
to be so here.
* R-Node
R-Node itself is covered by the license as described in the LICENSE
file.
* SHJS
SHJS uses the GPLv3.
