yaml header with 'params' --> Unable to tagle file

[r-cheologist]

I have a bookdown project where a yaml header contains

params:
  short: false

which is a custom parameter I use to compile two different variations of the same report from one source. Packrat is unable to gracefully deal with this and when I hit "Check for package updates", it reports:

Unable to tangle file '<MYFILE>.rmd'; cannot parse dependencies
Error in eval(x, envir = envir) : object 'params' not found

Sincerely, Joh

Related to #363 ?

I can't reproduce the issue as described. I can successfully tangle this file:

---
title: "Untitled"
output: html_document
params:
  short: false
---

# Hello, world!

Can you provide a reproducible example?

This problem was caused by using rmarkdown::render to analyze R Markdown files for dependencies.

We believe that this is resolved with #647.
