This is very cool. Two suggested edits for tl;dr :\

1. change "data=demand" to "data=demand1" in the third line of the
   call to ggplot.\
2. include your curve_intersect function in tl;dr.

Dude, there's no fucking brezier in Hmisc.

I just ran `Hmisc::bezier(c(1, 8, 9), c(1, 5, 9))` with Hmsic 4.0-3
and it's most definitely there...

Yeah, you're right, the %>% was the problem. What is that for?

Anyway, now "ggplot2 doesn't know how to deal with data of class
list" and also "

could not find function "curve_intersect" so I'm done and very
frustrated.

%>% comes from the magrittr package (which is part of the tidyverse)
and it lets you pipe left-hand side values forward into expressions that
appear on the right-hand side (see this chapter in the R for Data
Science book:
http://r4ds.had.co.nz/pipes... "http://r4ds.had.co.nz/pipes.html)").
It also gets loaded when you load dplyr

curve_intersect() is a custom function that's defined earlier in the
blog post.
