[R-gui] R web based application

[Wayne.W.Jones at shell.com]

Thanks to everyone for responding to my rather general query on building a web app with R. 

I have decided to investigate in further detail ASP.NET and connect to R using R(D)Com, see http://sunsite.univie.ac.at/rcom/  .

Indeed this method has already been partly tried and tested, see: 

http://www.msbi.nl/R/Demo.htm from the Leiden University
Medical Center website, for an example web app built with this arcitechture.

Some details on implemenatation are given here: 

http://www.msbi.nl/dnn/Default.aspx?tabid=159

I will keep you posted on my progress. 

Regards

Wayne

Speaking of ASP.NET, are there packages that allow an ASP.NET 
application to use an R back end for statistics? I went looking for 
statistical back ends to ASP.NET and didn't find anything that I thought 
was worth spending money for.
