Also, and while this is the Rcpp list: consider data.table. I use it a lot
these days, and "done right" it can be tremendously fast. I do some things
with it now for which I would have written Rcpp-based helpers in the past.

One tutorial I liked a lot is "Life in the Fast Lane: data.table Intro and
Best Practices" by Bill Gold at the NY HackR Meetup:
 - one-hour video https://www.youtube.com/watch?v=ztTDLefpPVY
 - slides repo https://github.com/billcgold/presentations/tree/master/data.table-nyhackr_2018-09-17

There are some excellent questions and answer for it at stackoverflow.
