Profiling and unit testing are also valuable, and I strongly recommend using a debugger. Sometimes lint programs can pick up on bugs. I would not expect this of students trying to learn how to use functions and objects from developed R packages, such as lm. Rather it is advice for those that are starting to implement non-trivial math or logic themselves, which could be in a collection of scripts or could be an entire package.

What is your Name/Contact Information? I am teaching Research Methods and am linking some of your content in my course shell. Trying to attribute these/credit to meet OER guidelines. I also have a few questions. Thanks!
