[Rd] Using R from Java
Hello, I am interesting in using R from a web application, for basic statistics and plots. The server is Java-based (tomcat). The simplest solution is a system call that generates the text or the image, then the servlet forwards the output. This can be done from any language, but it is quite inelegant and slow for the initialization time. Is there any package or approach for accessing R from a Java servlet you can suggest? Thanks in advance for any suggestion.

Re: [Rd] package config file for windows
Thanks for your answer. You confirm what I fear, it is not easily possible to test for SSE2 support on windows. Can I assume there exists inttypes.h on windows platform?

We're unlikely to drop tools from that collection, so this advice should last quite a while.

Can I assume there exists inttypes.h on windows platform? I think you misunderstood. The test scripts produced by autoconf won't necessarily work on Windows, but it's still worth trying. Just extract the tests for SSE2 and inttypes.h from your script on some other platform, and adapt them to Windows. They can probably be shortened, because there's less variability. You can count on Windows using gcc 4.x for current and future versions, probably until 5.x becomes commonly used. I don't know if inttypes.h is guaranteed in all of those, but it is currently present.

The FAQ has a section on R Web Interfaces http://cran.r-project.org/doc/FAQ/R-FAQ.html#R-Web-Interfaces include R/Apache and RServe. There is also Bioconductor's RWebServices, http://bioconductor.org/packages/2.2/bioc/html/RWebServices.html which produces soap-based web services from (strongly-typed) R packages.
