I'm debating about leaving it like this and just gliding right through this argument OR adding some more steps to this and asking the participants whether they notice that their are NAs in this set.

I guess main question is how much time we want to devote to this NA thing.

I think it is fine as is. This is a place where live coding should work well.
Note that the comment you have here will be stripped out, as only full line comments are kept. In this case, I think this is a good thing! It means that somebody looking at the rendered notebook will see the full explanation, but live participants won't see it before somethin goes 'wrong'.

Ah good point. I wasn't thinking about the live-ness part.

I'm using the word "environment" here but I realized that this notebook uses the word "environment" a couple of different ways, to refer both to the overall interface, and to the variables that are present in the "workspace", shown in the Environment pane.

We should try to standardize on a single meaning for each word, if we can. Unfortunately, RStudio uses "workspace" (load/save/clear workspace) and "environment" (the name of the pane) in its interface to mean mostly the same thing, but it does mean that both of those words are problematic to describe the whole shebang, as we do on line 47 (and in the objectives).
Maybe we should call it the "RStudio Interface" which I don't love, but don't have anything better right now.

Yes. This is good thing to streamline, but probably outside the scope of this PR. I'll make an issue for it.

Summary:
Closes #317
I went through intro_to_base_R.Rmd and replaced steps that used iris with penguins!
Here's the main drawbacks or changes we may want to discuss:
mean()step I had to use ana.rm = TRUEI don't like adding in an argument so soon, but if there's a better way to explain it or circumvent it, let me know.
