I (only! but luckily!) recently got introduced to the magic of purrr::reduce(). Thank you, Tobias! I was told about it right as I was unhappily using many for loops in a package1, for lack of a better idea. In this post I’ll explain how purrr::reduce() helped me reduce my for loop usage. I also hope that if I’m doing something wrong, someone will come forward and tell me!

nzchar(): “a fast way to find out if elements of a character vector are non-empty strings” One of my favorite testing technique is the escape hatch strategy, about which I wrote a post on the R-hub blog: you make part of your code responsive to an environment variable, and you locally set that environment variable in your tests.

I’m happy to report that I thought “oh but I know a better way to write that code!” a few times lately when reading old scripts of mine, or scripts by others.

I’ve tooted about all three things I’ll present in this post: After reading Julia Evans’ post about blogging, I decided to train the blogging muscle a bit using these low-hanging fruits/toots1.
