Submitted by erik on

As the number of R users and contributed packages increases, activity on the R-help mailing list and the R tag on Stack Overflow also continues to rise. Users with the knowledge to help those asking questions naturally have limited time to assist on these forums. In order to get the best answers in the shortest amount of time, there are definite steps you can take as a poster to ask high-quality questions.

Introduction to using R with org-babel, Part 1

Submitted by erik on
This post originally appeared on my Wordpress blog on May 23, 2010. I present it here in its original form.

In my opinion, the description of orgmode by its creator as a tool "for keeping notes, maintaining ToDo lists, doing project planning, and authoring with a fast and effective plain-text system" is a little like describing Emacs as a "text editor". While technically accurate, one not acquainted with orgmode might not be immediately persuaded to learn it based on its pedestrian description. Needless to say, I think it is worthwhile.

Making Emacs Buffer Names Unique Using the Uniquify Package

Submitted by erik on

This post originally appeared on my Wordpress blog on October 5, 2009. I present it here in its original form.

If you ever work in Emacs with different files that all have the same name, this tip may be very useful for you. In my experience, this most often happens when working with Makefiles from multiple projects or directories. Assuming you have a buffer visiting a file called Makefile, by default Emacs will call the second buffer Makefile<2>. This is not very useful for figuring out which one is which.

Using doc-view with auto-revert to view LaTeX PDF output in Emacs

Submitted by erik on

This post originally appeared on my Wordpress blog on October 3, 2009. I present it here in its original form.

When I am authoring a LaTeX document in Emacs, such as a report or my CV, it is useful for me to compile the LaTeX source file periodically to see what the resulting file PDF looks like. I used to run a separate PDF viewer to look at the output, but I now have a complete Emacs solution.

R Object Tooltips in ESS

Whether at work or for personal projects, I use ESS a lot to perform interactive data analyses. The ability to write, edit, and submit R commands to an interactive R process is simply something I cannot imagine analyzing data without.
