[R] Best settings for RStudio video recording?

Excellent question! I think most R courses use RStudio, so it is completely
appropriate to ask about how to help people learn R using RStudio.

I don't have a lot experience with virtual teaching, and very limited
experience with anything other than short-term workshops.

I think that there is tremendous value, during the 'in person' portion
of a course, in doing interactive and even 'ad hoc' analysis, perhaps
especially handling the off-the-wall questions that participants might raise
(when I have to struggle to figure out what the R answer is, and then convey to
the attendees my thinking process), and making all kinds of mistakes, including
simple typos (requiring me to explain what the error message means, and how I
diagnosed the problem and arrived at a solution that was other than a
pull-it-out-of-the-hat miracle).

With this in mind, I try to increase the prominence of the console portion of
the RStudio interface. I place it at the top left of the screen (this might be a
remnant of in-person presentations, where the heads of people in front often
block the view of the lines where code is being enter; this is obviously not
relevant in a virtual context). Usually I keep the script portion of the display
visible at the bottom left, with only a few lines showing, as a kind of cheat
sheet for me, rather than for the students to 'follow along').

I use a large font, which I think helps in both virtual and physical sessions in
part because it limits the amount of information on the screen, causing me to
slow my presentation enough that the students can absorb what I am saying.
Perhaps as a consequence of the limited screen real-estate, students often ask
'to see the last command' so I now include in the right panel the
'History' tab. The division is asymmetric, so the console continues to
take up the majority of screen real estate.

The end result of a sequence of operations is often a pretty picture, but since
this is only the end result and not the meat of the learning experience I tend
to keep the plot window (lower right) relatively small, and try to remember to
expand things at the time when the end result is in sight (so to speak;)).

I hope others with more direct experience are not dissuaded by Bert's
opinions, and offer up their own experiences or resource recommendations.

    Folks:

    I was wondering if you all would suggest some helpful RStudio
    configurations that make recording a session via e.g. zoom the most useful
    for students doing remote learning.  Thoughts?
