Subsetting Vectors in R

Apr 10, 2015 • Heather Gibling

Here is my practice teaching video for programming in R.

I chose the bit on subsetting character vectors from the first R lesson (Analyzing Patient Data), as my first practice teaching was on subsetting data tables.

Feedback from my teammates was positive. They mentioned that it flowed nicely and that there weren’t many ‘uhhs’ and ‘umms’ (though I hear so many!), and suggested that I add a bit of an explanation of why I would want to do something (like reverse the subset, or remove an instance) instead of just doing it.
