February 1, 2014
By

Eventually we get around to teaching our students to turn in Homework assignments as R Markdown documents, and towards the end of the semester many of them will do a data analysis project, complete with a report generated as an HTML file. But frankly the HTML output is a bit ugly. What if students want something that looks a...

(Added May 19, 2014: On May 17 R Stduio announced a preview release of version 0.98b which will render moot the techniques described in this post, as the new version provides built-in options to convert from R Markdown to PDF and to Word formats.)

Lies, Damn Lies, “Data Journalism” and Charts That Don’t Start at 0

This tweet by @moorehn (who usually is a superb economic journalist) really bugged me: Alarming chart of employment for people between 25 and 54. It's like a ski jump. #SOTUecon pic.twitter.com/KNGYmwI88C— Heidi N.

For several year's I've maintained a page of resources somewhat grandiosely headed "Writing and Presenting Social Science".
