There is a very nice Mediawiki plugin for R which allows you to embed R code in any wiki page. It takes a little effort to configure, but it's really useful once you have it in place.
Does anyone know of an equivalent for embedding R in a blog post? The only thing I could find was this wordpress plugin called RWebFriend, but it only allows you to send code to Rweb. I'm envisioning something where you can embed your code between two tags and it is executed and returned.
You may have to integrate R into your blogging engine, not unlike the MediaWiki extension.
Or, going the other way, you take Rpad and wrap a blog engine around its web-based R interface.
I see that there is a posting on this very subject on the "Learning R" blog today. What a coincidence!
This uses Sweave to create the actual output, along with a Python script called blogpost.py (from Stuart Rackham) to upload the results onto the Wordpress blog. I like that approach because using Sweave means that your blog output could easily be converted into a paper or a presentation (with Beamer), so blogging becomes even more useful in the long run.
There's a post on Blogistic Reflections blog how he is using Emacs/ESS org-mode to get the HTML export functionality.
Most blogging software has an XML-RPC interface. So the easiest way to blog from R, could be by using this package: http://www.omegahat.org/XMLRPC/ and RCurl which can also be found on that site.
This would be by far the easiest way to go. If you google XML-RPC and Wordpress you can find code written for php, but it could help for writing the R code as well.
Hi Shane. I see you asked this a year ago, and since there has been some updates since (relevant to WordPress blogs), I thought of referencing them.
I wrote two posts on the topic:
p.s: I also published the talk I gave on useR2010 with other tips on blogging about R, but the other the posts linked to are the ones answering your question.
Cheers, Tal
