R markdown format title - pdf output

Question

I'm sure this is already out there but I can't seem to find it. How can I change the font size and spacing for the title in an R markdown document compiled as a pdf?

Thanks!

Answer 1

I'm not sure exactly how you want the document to look, but here are some ways to control spacing and fontsize with Latex tags. In the rmd document below:

1. The initial \vspace{5cm} adds space above the first line of the title. \vspace{0.5cm} adds space between the two lines of the title.
2. \LARGE and \Large give different font sizes on different lines of the title.
3. | at the beginning of each line of the title allows a multi-line title.
4. If you want a separate cover page, \newpage at the beginning of the main document will start the main document text on a new page after the title page.

title: | 
  | \vspace{5cm} \LARGE My Title is really long and takes up several lines of text
  | \vspace{0.5cm} \Large My Title is really long and takes up several lines of text
author: "eipi10"
date: "5/16/2017"

Answer 2

For a smaller title section, the following may be helpful. It builds on eipi10's answer but with two modifications:

1. the vspace{} commands include negative values to shrink white space
2. the fontsize code uses the more cumbersome begin{} and end{} syntax because, with simpler code like \normalsize{}, I found extraneous braces appeared around the title, name, etc.
