rApache is a project supporting web application development using the R statistical language and environment and the Apache web server

rApache is a project supporting web application development using the R statistical language and environment and the Apache web server. The current software distribution runs on UNIX/Linux and Mac OS X operating systems. Apache servers with threaded Multi-Processing Modules are now supported, but the the Apache Prefork Multi-Processing Module is still recommended (refer to the Multi-Processing Modules chapter from Apache for more about this).

The rApache software distribution provides the Apache module named mod_R that embeds the R interpreter inside the web server. It also comes bundled with libapreq, an Apache module for manipulating client request data. Together, they provide the glue to transform R into a server-side scripting environment.

Another important project that's not bundled with rApache, but plays an important role in server-side scripting, is the CRAN package brew. It implements a templating framework for report generation, and it's perfect for generating HTML on the fly. It's syntax is similar to PHP, Ruby's erb module, Java Server Pages, and Python's psp module. brew can be used stand-alone as well, so it's not part of the distribution.
