Welcome to the Rpad home page

Rpad is an interactive, web-based analysis program. Rpad pages are interactive workbook-type sheets based on R, an open-source implementation of the S language. Rpad is an analysis package, a web-page designer, and a gui designer all wrapped in one. Rpad makes it easy to develop powerful data analysis applications that can be shared with others (most likely on an intranet). The user doesn't have to install anything--everything's done through a browser.

Dojo Version of Rpad

The client-side code for Rpad 1.x has been re-engineered. It is based on Dojo, a flexible javascript toolkit. The main advantages made possible by Dojo are:

This new version also has a number of other improvements:

The old client code is still present, so old pages *should* work without change (example). See here for a list of changes needed for new pages.

How to Run Rpad

Rpad can be set up with a webserver like Apache, or Rpad can be run locally using a built-in webserver. Install Rpad as an R package. Run it locally or install it on a server. To run it locally after installing the Rpad package into R [install.packages("Rpad")], just use the following to start Rpad from within R:

library(Rpad) 
Rpad()

This runs a mini webserver and launches your browser to an Rpad startup page. This version can also be installed server-style with Apache (tested on windows and linux) or another server.
