This short posts contains
from the online teaching session with Violet Zhang and myself on April 13. I
chose a topic related to R package building and particularly unit testing
given the simplest R mechanism: the
tests/ directory a package can contain.
Violet was once again very polite yet concise. Some of the material may be a little too advanced. I also stumbled over some things not prepared yet — but that comes with the territory of live coding in a lesson.
