I briefly talk about and demo my experience of using the (currently experimental) redoc R package for dealing with comments and tracked changes in MS Word documents produced by RMarkdown.
redoc is an R package by Noam Ross that enables a two-way R Markdown-Microsoft Word workflow. It generates Word documents that can be de-rendered back into R Markdown, retaining edits on the Word document, including tracked changes.
UPDATE: redoc was updated on May 5, 2019 so some aspects of the talk are now out-of-date. For example
undoc() has been replaced by
redoc_diff() lets you view changes more easily.
