I'm collaborating with a team of researchers on a project where we use Rmarkdown to analyze data and create reproducible reports. We have a GitHub repository and changes are routinely pushed to the remote server.
I would like to be able to comment and make changes to my teammates' code such that they can later see the changes in RStudio and address them one by one. Normally I do this with a pull request but I'm not sure how they will then be able to see my changes highlighted within RStudio, if it's possible at all. So my question is what is the best pipeline for collaborating on a long RMarkdown file?
