FastRWeb is an infrastructure that allows any webserver to use R scripts for generating dynamic content, such as web pages and graphics.
In this post, you’ll learn how to install and set up FastRWeb on a Mac. This tutorial is expendable to any Unix-like operating system. It is an adaptation from Jay Emerson’s post, Setting up FastRWeb/Rserve on Ubuntu.
- J. Emerson, Setting up FastRWeb/Rserve on Ubuntu, October 2011. 2012-02-22.
- S. Urbanek, Package ‘FastRWeb’, February 2012. R package version 1.1-0.
- www.rforge.net/FastRWeb 2012-02-22.
- www.rforge.net/Rserve 2012-02-22.
- Mac OS X 10.6.8
- R 2.14.1
- XAMPP 1.7.3
- Apache 2.2.14 (via XAMPP)
- FastRWeb 1.1.0
- Rserve 1.7.0
- Cairo 1.5.1
- XML 3.93.0
Even if not required, I recommend installing the latest version of the XML package. An older version may cause a dysfonction. You should install it from sources.
ftp http://www.omegahat.org/RSXML/XML_3.93-0.tar.gz R CMD INSTALL XML_3.93-0.tar.gz
Cairo is a graphics device for R which uses the cairo graphics library. You can easily install it using MacPorts or Fink. In the terminal, install Cairo from sources.
ftp http://www.rforge.net/Cairo/snapshot/Cairo_1.5-1.tar.gz R CMD INSTALL Cairo_1.5-1.tar.gz
I use the Apache HTTP Server from XAMPP because it comes pre-configured to run CGI scripts. You may want to use the server pre-installed on Mac OS X. Then, you will have to configure it to run CGI scripts.
To install Rserve, you have to use a recent version of R (≥ 2.0.0). As the other packages, you should install it from sources.
You will need administrator privileges to install it.
ftp http://www.rforge.net/Rserve/snapshot/Rserve_1.7-0.tar.gz sudo R CMD INSTALL Rserve_1.7-0.tar.gz
If the installation is okay, try to run Rserve in R.
As the other packages…
ftp http://www.rforge.net/FastRWeb/snapshot/FastRWeb_1.1-0.tar.gz sudo R CMD INSTALL FastRWeb_1.1-0.tar.gz
FastRWeb isn’t a simple R package, it is an environment for servers to run R scripts. To do this, you must go to the folder where is the FastRWeb package.
cd `echo 'cat(system.file(package = "FastRWeb"))' | R --slave`
FastRWeb privides a sample script install.sh that sets up the environment. You can run it like this:
sudo sh install.sh
FastRWeb will be installed in
Now you can copy the CGI program named Rcgi which is in the directory
cgi-bin of the package to the directory
cgi-bin of the server. You’ll have to use the administrator privileges.
sudo cp cgi-bin/Rcgi /Applications/XAMPP/xamppfiles/cgi-bin/R
Starting the server
Now, you can run the Apache HTTP Server with XAMPP Control.
open -a /Applications/XAMPP/XAMPP\ Control.app
Start Rserve with the administrator privileges.
Try the example
If you can see the examples, you can start developping your own scripts.
To stop FastRWeb/Rserve.
sudo killall -INT Rserve
You may want to remove sources.
