Protovis, R and nodejs

[Jamie Love]

Hi all,

I thought some of you may get some enjoyment out of this.

I've created a web based frontend for the statistical analysis package 'R', using protovis for drawing graphs. See the attached screenshots for a bit of a teaser.

It uses Protovis, jquery and ExtJS core on the front-end. Most R commands are passed back to the server and their results returned to the client. Some, such as the graph commands, are parsed and the arguments used in javascript re-implementations of the R commands (e.g. the R command 'plot' has a protovis equivalent).

The server side is R+Rserve, and to connect the browser client to the R server I use a nodejs based application server.

I will be uploading the code to Gitorious in the near future (once I get the licenses sorted out).

The http://cran.r-project.org/doc/manuals/R-intro.pdf file includes "a sample session". The frontend can be used to run most of this sample session.

Projects I've utilised in this include:

Protovis - http://vis.stanford.edu/protovis/
Nodejs - http://nodejs.org/
R - http://www.r-project.org/
Rserve  - http://www.rforge.net/Rserve/doc.html
Shjs - http://shjs.sourceforge.net/


PS: I realise that a demo is significantly better than screenshots, and even had a jail'ed R instance set up and running, but have decided to not provide a link as R provides to much significant access to the server (via it's system commands). If you're interested in having an interactive session, please email me privately.

In the second screenshot you see the results of the R command 'plot(x, y)' (with my reimplementation of plot doing the actual plotting), and in the fourth screenshot you see a similar plot command along with a subsequent best fit line (data points calculated with 'lowess()') drawn in.

Regards
Jamie

Very cool! Any chance you're going to open source this?

Jamie,
that's pretty freakin' awesome. Will be waiting impatiently to see a
live version!

Awesome, Jamie! This is very exciting. Looking forward to playing with
the demo and seeing the source!

Thanks everyone for the enthusiasm.

To answer Robert's question, yes it is going to be open-sourced. I'm just getting the licensing sorted, and writing an INSTALL file and makefile.

Hi all,

For those that are interested, you can find the source code for this
system at:

http://gitorious.org/r-node

Some simplistic install instructions are included. If you have trouble
or questions, email me privately.

Now that I've got all that sorted out... back to adding more
features.
