How to create a combined PDF of component rmd documents?

[jeromyanglim]

I'd like to create a combined PDF document.

A basic workflow

• Convert Each RMD file to MD to LaTeX
• Combine all LaTeX files into one larger LaTeX file (perhaps using \input
• Convert combined LaTeX file into PDF

Ideally,

• The PDF would have a table of contents
• Equations are passed through
• Code formatting is attractive
