Such behavior does not exist in current dplyr joins, though it has been discussed, and so may someday. For now, let’s build an coalesce_join function.

In particular, I have been reading David Robinson’s lovely Introduction to Empirical Bayes: Examples from Baseball Statistics and watching Rasmus Bååth’s delightful three-part Video Introduction to Bayesian Data Analysis, notable amongst other videos, courses, and textbooks. I have much yet to learn, but my past experience with statistics has taught me that I understand concepts most thoroughly by actually implementing them. Thus,…
