The R-Podcast

Giving practical advice on how to use R for powerful and innovative data analyses.


What is a podcast? A podcast is an audio file that can be downloaded and played on a computer or portable audio device. Despite the name “podcast,” you can listen to the R-Podcast on your computer or any portable audio device capable of playing MP3 or Ogg Vorbis audio files.

What is a screencast? A screencast is a video with audio narration.  You can watch the screencast episodes directly on the R-podcast web site, or you can directly download high-quality versions of the video using the direct links posted with each screencast.  Most video players should be able to play the screencasts without a problem. I recommend VLC as a robust media player that is available on Windows, Linux, and Mac. If you would like to subscribe to the custom RSS feed for the screencasts, you can use the following RSS feed:

For whom is this podcast intended? This podcast is intended for both new and experienced R users who are interested in the exciting and innovative ways R can be used to produce powerful and robust data analyses and visualizations.

How long will each episode be? The length of each episode will depend greatly on the topic.  For the episodes that introduce a topic, the length will be roughly thirty minutes.  For advanced topics and the screencasts, the episodes may approach sixty minutes in length.

Will you consider audience requests for episodes? Yes! Please send email or audio feedback to thercast[at] or leave a voicemail at +1-269-849-9780.

Will you answer technical questions submitted by email or audio feedback on the air? It will depend on the time constraints for each episode and on whether the question is suited for the audience. But, answering feedback and questions on the air is a very high priority.

How often do you plan on releasing new episodes? This will depend on user interest. At the outset, new episodes will be released periodically with no set schedule. However, if user interest is high, then a more regular schedule will be established.

What is Ogg Vorbis? In short, Ogg Vorbis is a free and open-source audio codec, similar to MP3 or AAC. Many audio enthusiasts believe that an Ogg Vorbis version of an audio file will have superior sound and take up less disk space than a comparable MP3 version of the same audio file. Please see the Wikipedia entry on Ogg Vorbis for more information. The R-podcast will be offering Ogg Vorbis versions of each episode to support this free and open-source audio codec.

  • What audio players support Ogg Vorbis? Most of the players offered byCowon do, as do some of the players made byiRiver and SanDisk.

What technical tools do you use to record and edit the podcast?

  • Audacity, an open-source cross-platform audio editor and recorder, is used to record the shows.
  • Episode show notes are written in markdown format using a variety of text editors or IDEs such as vim, Sublime Text, Atom, and Remarkable.
  • Each epsiode is hosted on the Internet Archive
  • The R-Podcast site is written using the Nikola static site generator and hosted on Digital Ocean virtual servers running Linux.
