Customising your document using the YAML header

• A YAML Header (“Yet Another Markdown Language”) tells you the core details of your document
• You can customise your YAML header to produce a pdf_document, html_document or word_document
  • nb this can also be done by selecting options in the “knit” dropdown menu
• be careful with YAML indents and colons
  • sub-items should be started in a new line (with an indent) and NOT directly after the colon
  • it can be directly after the colon if it refers to that item itself (see above YAML header)
• add a table of contents as toc: true and toc_float: true
• You can also change the theme of the output. Play around with the below themes!
  

output:
html_document:
theme: default, cerulean, journal, flatly, darkly, readable, spacelab, united, cosmo, lumen, paper, sandstone, simplex, yet
