Use of par(mfrow) and grid.arrange

[eshab5]

Hi,
I have a small suggestion for the lesson "programming with R". While reviewing the first episode "Analysis of patient data" it was great to see how learners can produce plots for three different things- namely average_day_inflammation, max_day_inflammation, and min_day_inflammation.
I feel here, we can additionally show them how it is also possible to view the three plots together in a single window instead of running each command separately.
This can be done by using the function
par(mfrow=c(1,3))
plot(avg_day_inflammation)
plot(max_day_inflammation)
plot(min_day_inflammation)

Similarly, we can also show them how to produce multiple ggplots in a single window using the function grid.arrange()

Hi. Thanks for the suggestion!

Would you consider it a good idea to put it in the lesson itself or have a separate lesson on graphing? The rationale behind the latter might be that over the course of a live workshop participants would want to play around with the graphing a lot more.

Hi,
Yes, I think the latter sounds good (having as a separate chapter altogether).

Thanks, @eshab5. I will bring it up with the course development team. Perhaps @diyadas might chime in here as well.
