R web application introduction

Question

I doubt this is the right place to ask the question, but I was wondering if there is a good place for an introduction to developing web apps in R. I know people are doing it and I know about where to find out about RApache and brew but any kind of walkthrough?

Just checking before I start on my own.

Answer 1

One important first step is getting R on a web accessible server. R+EC2 is a good start.

Answer 2

There are lots of different ways of creating a web app with R. Most (if not all) are listed in the FAQ on R document.

If you want to use RApache, there's a presentation on the old RApache site that might be useful to get you started. Otherwise, RWui is very simple to use, but not so flexible (last time I used it, anyway), and rcom/StatConnector can be used to run R from your web server.

Answer 3

Check out Jeroen Ooms' useR!2009 presentation - this also contains an example. I believe Stockplot R web application has been built using the same techniques.

Answer 4

I just came a cross this old question.

There are three, newer, videos you can watch:

1. R Web Application – “Hello World” using RApache (~7min video tutorial)
2. Web Development with R – an HD video tutorial of Jeroen Ooms talk
3. A web application for R’s ggplot2

(I could have linked just to the youtube videos, but the posts also includes extra links to code, presentations and explanations)
