The present and future of the R blogosphere (~7 minute video from useR2011)

This is (roughly) the lightning talk I gave in useR2011. If you are a reader of then this talk is not likely to tell you anything new. However, if you have a friend, college or student who is a new useRs of R, this talk will offer him a decent introduction to what the R blogosphere is all about.

The talk is a call for people of the R community to participate more in reading, writing and interacting with blogs.

I was encouraged to record this talk per the request of Chel Hee Lee, so it may be used in the recent useR conference in Korea (2011)

The talk (briefly) goes through:

  1. The widespread influence of the R blogosphere
  2. What R bloggers write about
  3. How to encourage a blogger you enjoy reading to keep writing
  4. How to start your own R blog (just go to
  5. Basic tips about writing a blog
  6. One advice about marketing your R blog (add it to
  7. And two thoughts about the future of R blogging (more bloggers and readers, and more interactive online visualization)

My apologies for any of the glitches in my English. For more talks about R, you can visit the R user groups blog. I hope more speakers from useR 2011 will consider uploading their talks online.

R syntax highlighting for bloggers on

Good news for R bloggers who are using to host their blog.

This week, the good people running (special thanks goes to Yoav Farhi), have added the ability for all the users of the platform to be able to highlight their R code inside posts.

Basically you’ll need to wrap the code in your post like this:

[sourcecode language="r"]
test.function = function(r) {
    return(pi * r^2)

(Which will then look like this:
r syntax highlighted code example

Further details (and other supported languages) can be read about on this support page.

This new feature was possible thanks to the work of Yihui Xie (who create the famous cool animation package for R), who created a R syntax brush for the syntaxhighlighter WordPress plugin (the plugin used by for sytnax highlighting) . And thanks should also go to Andrew Redd, the creator of NppToR (which connects between notepad++ to R). He both made some good suggestions, and was game to take on the brush creation in case there would be problems, which thankfully so far there aren’t any)

p.s: If you are a users (e.g: have a self hosted WordPress blog) and want to enable R syntax highlighting for your blog, I would recommend the use of the WP-Syntax plugin (enhanced with GeSHi version which can be downloaded here.
