citation functionality not mentioned
As datacarpentry is aimed at researchers, citations are an important part of their job. Therefore a page on Rmarkdown should mention citations.
Maybe just one sentence about it including a link that is a more up-to-date version of https://www.rstudio.com/blog/rstudio-1-4-preview-citations/
@steltenpower -- I would agree! This could also be a great place to add a short blurb about the citation() function in R. Would you be interested in putting in a pull request for this content?
@atheobold -- I have just done the instructor training and would like to contribute to solving this issue as part of my checkout. I would be interested in putting in a PR for this. Let me know, other than the above, what you may have had in mind.
@AvdReis that would be great! i don't have any insight into this, so please use your judgement
