Edit title slide of R Markdown Slidy Presentation

Question

Is there a way to edit the title slide of a R Markdown Slidy Presentation? I am able to add the header, footer, and custom css:

title: "Slidy Template"
author: ""
date: "June 18, 2015"
runtime: shiny
output: 
  slidy_presentation:
    css: ./styles/Slidy_Styles.css
    includes:
      after_body: ./styles/doc_suffix.html
      before_body: ./styles/header.html

But I can't figure out how to either add anything besides title, author, and date to the slide, or else replace the standard slidy title slide with a custom html template, like I do with the header and footer.

Is there a way to do this?

Answer 1

You can modify the part about title page in the pandoc slidy template, also found with pandoc -D slidy.

$if(title)$
<div class="slide titlepage">
  <h1 class="title">$title$</h1>
$if(subtitle)$
  <h1 class="subtitle">$subtitle$</h1>
$endif$
  <p class="author">
$for(author)$$author$$sep$<br/>$endfor$
  </p>
$if(date)$
  <p class="date">$date$</p>
$endif$
</div>
$endif$

Save the resulting file as default.slidy in your pandoc template directory :

$HOME/.pandoc/templates (unix)
C:\Documents And Settings\USERNAME\Application Data\pandoc\templates (windows XP)
C:\Users\USERNAME\AppData\Roaming\pandoc\templates (windows 7)
