Re: [R] How to get R plots with FastRweb

FastRWeb doesn't use Java - it is entirely R based so all you need is a web server with either CGI or PHP. The client it uses is either a C++ client (part of FastRWeb in the cgi-bin directory of the installed package - just copy to you server's cgi-bin) or a PHP client (in Rserve/src/client/php/simple.php - simply uncomment process_FastRWeb()). The location of the R scripts it serves is defined by PROJECT_ROOT at the time you compile FastRWeb which is by default /var/FastRWeb so by default foo.png.R would be /var/FastRWeb/web.R/foo.png.R

Clearly, you could use Java to connect to the Rserve serving FastRWeb but it sort of defeats the purpose, because FastRWeb does all the work for you consisting of parsing the request and running the scripts.

If you still have issues, I can point you to a sample configuration including the setup etc. (for a unix server) if that helps.

As R produces more interactive plots, I would also like to pipe plots generate from R on web page. I came to know that FastRWeb, R2HTML, brew and WebGraphics, Cairo together can be used to do that. I have installed all those successfully. I am developing my web service project with NetBeans. For testing purpose I have used the excersie (kmeans) given in the FastRWeb document.I have put the kmeans.png.R program in my netbeansProject/R directory where other java code runs properly.
