Lesson 4 feedback

[Gammerdinger]

I am not very well-versed in tidyverse, but it might be nice to give a bit more context to what pivot_longer is exactly doing. I figured it out after a bit, but putting it into words would be nice. The join command seems like complete magic to me. It looks like it works, but I have no clue how. A bit more explanation there would be useful.

I think I might suggest we start people off with:

ggplot(pax6_exp) + geom_boxplot(aes(x=group, y=normalized_counts))

for the exercise. I had a bit of trouble getting that foothold. I wasn't sure if I should use expression_plot. Also, lots of the syntax is just new in general, so giving people a foothold might be nice.
