In RStudio, making slide deck with RMarkdown, how can I easily change the theme?

I'm writing an .rmd file in RStudio, and using the Knit button to create a slide deck. I have two options, it appears, ioslides and slidy. I don't really like the default look-and-feel of either. (I think ioslides uses screen real estate inefficiently, and slidy feels like a graphic designer wasn't involved.)

I did a web search for alternative templates/styles/themes, and came upon pages like this gallery, but the tools there seem to be for use outside RStudio, as completely independent projects. In other words, they're not just themes for what I've got, but entirely other solutions that would change my workflow.

Is there a simple way to tell RStudio to use a different template/theme with either ioslides or slidy? For example, can I download a CSS file from somewhere, and point RStudio to it with the css: option in the yaml header of my .rmd file? If so, is there a gallery of such CSS templates?

Solution

  • Here's what I ended up doing. It's not as smooth as I'd like it to be, but it's decent. I'm glad to entertain better answers.

    1. Download any of the style files linked to from this knitrBootstrap code into the same folder as your R Markdown file.
    2. Edit it so that the URL at the start of the file begins with http: so that knitr knows not to look on your filesystem for the additional resources (fonts), but on the Web.
    3. Edit it further to remove any pipes (|) in that URL, because knitr can't handle them (as far as I can tell). (Remove everything after the pipe, too.)
    4. Edit it further to change everything of the form url('../fonts/***.eot'); to now instead be of the form url('https://netdna.boostrapcdn.com/bootswatch/3.0.0/fonts/***.eot');.
    5. Link to it from your R Markdown file with the css: attribute in the YAML header.
