some bootswatch 3 themes fail for rmarkdown websites

[maxheld83]

I've just set up an rmarkdown website from the boilerplate that ships with RStudio 1.2.5013, just adding a different bootswatch theme:

_site.yml:

name: "my-website"
navbar:
  title: "My Website"
  left:
    - text: "Home"
      href: index.html
    - text: "About"
      href: about.html
output:
  html_document:
    theme: slate

(index.Rmd and about.Rmd are as in the boilerplate unchanged).

When running rmarkdown::render_site(), this fails with:

Error in navbarHeights[[theme]] : subscript out of bounds
Calls: <Anonymous> ... <Anonymous> -> overlay -> pandoc_body_padding_variable_args
Execution halted

Exited with status 1.

The problem seems to exist for themes:

• slate
• superhero.

cosmo and sandstone work.

Reproduces on another machine.

These themes were not added to the rmarkdown package. Available ones are documented on the help page ?rmarkdown::html_document.

They will be added when #1688 is done, but I have no idea how long it will take...

[maxheld83]

ah yes, sorry.

For future reference, ?rmarkdown::html_document:

Visual theme ("default", "cerulean", "journal", "flatly", "darkly", "readable", "spacelab", "united", "cosmo", "lumen", "paper", "sandstone", "simplex", or "yeti"). Pass NULL for no theme (in this case you can use the css parameter to add your own styles).

I was under the mistaken impression that all bootswatch 3.3.x themes were supported.

[yihui]

Perhaps we should just add these missing themes to avoid future confusion. If you could submit a PR, I'll be happy to review and merge it. Thanks!
