PR is ready for your review @jhollway.

• Note that I changed a bit how percent_female() works. I basically flattened the list of authors so as to deal with papers that have multiple authors.
• Also note that there is still a remaining warning related to the absence of {genderdata} from the NAMESPACE when running devtools::check()

Interesting approach with the problem sets. Is that what you need for your courses?

Note to self: Update the bibstats test.

A bit about the reasoning behind the problem set template for posterity

Econ classes at the Institute require students to hand in around 4-5 problem sets per course in teams or individually. These problem sets either are in the traditional "math problem" format where we work on models or are data analysis focused (e.g. applied econometrics) which often use Stata. The workflow I used for the past year was to perform the data analysis in Stata, generate deliverables (graphs, tables) in Latex code with estout, and pasting them in a shared Latex project on Overleaf.

Since this year's classes will rely more on R, I thought it would be neat to have a template ready for the start of the semester. I'll also create a vignette exploring the collaboration tools that exist for R as I test them over the course of the semester.

There seems to be an error when I try and run this:

! Package fontspec Error: The font "Latin Modern Roman" cannot be found.

! kpathsea:make_tex: Invalid filename `Latin Modern Roman', contains ' '

Error: LaTeX failed to compile MINT001_ProblemSet_2021-08-21.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See MINT001_ProblemSet_2021-08-21.log for more info.
Execution halted

Good spot! I have changed the fonts to be consistent with our thesis template and work via Latex packages rather than user system font imports. Could you confirm that it works now on macOS as well @jhollway ?
