Headers in Knitr

Question

Is there a way to use knitr from within the R console (not RStudio) to process a header. There are many examples using YAML headers such as:

---
title: "Habits"
author: John Doe
date: March 22, 2005
output: html_document
---

However, is there a way to have this header included using knit2html from within the R console? Thanks!

Answer 1

No, the YAML metadata is specific to R Markdown v2, i.e. the rmarkdown package. The knitr::knit2html() function is for R Markdown v1 only.
