is now two years young. The site is an (unofficial) online R journal written by bloggers who agreed to contribute their R articles to the site.
In this post I wish to celebrate R-bloggers’ second birthmounth by sharing with you:

  1. Links to the top 20 posts of 2011
  2. Statistics on “how well” R-bloggers did this year
  3. An invitation for sponsors/supporters to help keep the site alive

1. Top 24 R posts of 2011

R-bloggers’ success is largely owed to the content submitted by the R bloggers themselves.  The R community currently has almost 300 active R bloggers (links to the blogs are clearly visible in the right navigation bar on the ).  In the past year, these bloggers wrote over 2800 posts about R.

Here is a list of the top visited posts on the site in 2011:

2. Statistics – how well did R-bloggers do this year

There are several matrices one can consider when evaluating the success of a website.  I’ll present a few of them here and will begin by talking about the visitors to the site.

This year, the site was visited by over 665,000 “Unique Visitors.”  There was a total of over 1.4 million visits and over 2.8 million page-views.  People have surfed the site from over 200 countries, with the greatest number of visitors coming from the United States (~40%) and then followed by the United Kingdom (6.9%), Germany (6.6%), Canada (4.7%), France (3.3%), and other countries.

The site has received between 15,000 to 45,000 visits a week in the past few months, and I suspect this number will remain stable in the next few months (unless something very interesting will happen).

I believe this number will stay constant thanks to visitors’ loyalty: 55% of the site’s visits came from returning users.

牵手常德棋牌官方下载Another indicator of reader loyalty is the number of subscribers to R-bloggers as counted by feedburner, which includes both RSS readers and e-mail subscribers.  The range of subscribers is estimated to be between 5600 to 5900.

牵手常德棋牌官方下载Thus, I am very happy to see that R-bloggers continues to succeed in offering a real service to the global R users community.

3. Invitation to sponsor/advertise on R-bloggers

牵手常德棋牌官方下载This year I was sadly accused by google adsense of click fraud (which I did not do, but have no way of proving my innocence).  Therefor, I am no longer able to use google adsense to sustain R-bloggers high monthly bills, and I turned to rely on direct  sponsoring of R-bloggers.

If you are interested in sponsoring/placing-ads/supporting R-bloggers, then you are welcome to contact me.

Happy new year!

UseR! 2011 slides and videos – on one page

Links to slides and talks from useR 2011 – all organized in one page.

I was recently that the wonderful team at warwick University made sure to put online many of the slides (and ) of talks from the recent  conference.  You can browse through the talks by going between the  (where it will be the most updated, if more slides will be added later), but I thought it might be more convenient for some of you to have the links to all the talks (with slides/videos) in one place.

牵手常德棋牌官方下载I am grateful for all of the wonderful people who put their time in making such an amazing event (organizers, speakers, attendees), and also for the many speakers who made sure to share their talk/slides online for all of us to reference.  I hope to see this open-slides trend will continue in the upcoming useR conferences…

R-bloggers in 2010: Top 14 R posts, site statistics and invitation for sponsors

A year ago (on December 9th 2009), I wrote about founding , an (unofficial) online R journal written by bloggers who agreed to contribute their R articles to the site.

In this post I wish to celebrate R-bloggers’ first birthday by sharing with you:

  1. Links to the top 14 posts of 2010
  2. Reflections about the origin of R-bloggers
  3. Statistics on “how well” R-bloggers did this year
  4. Links to other related projects
  5. An invitation for sponsors/supporters to help keep the site alive

A nice link: "Some hints for the R beginner"

Patrick Burns just posted to the mailing list the following massage:

There is now a document called “Some hints for the R beginner” whose purpose is to get people up and running with R as quickly as possible.

Direct access to it is:

JRR Tolkien wrote a story (sans hobbits) called ‘Leaf by Niggle’ that has always resonated with me. I offer you an imperfect, incomplete tree (but my roof is intact).

Suggestions for improvements are encouraged.

And here is the link tree for the document (for your easy reviewing of the offered content) :
