This is part four of our four part series Part 1: Specifying the correct figure dimension in {knitr} (this post). Part 2: What image format should you use for graphics. Part 3: Including external graphics in your document. Part 4: Setting default {knitr} options. At Jumping Rivers we recently moved our website from WordPress to Hugo. The main reason for the move was that since the team are all very comfortable with Git, continuous integration and continuous development using a static web-site generator made more sense than WordPress.
