Hidden Features of C++? [closed]
... C++ programmers are familiar with the ternary operator:
x = (y < 0) ? 10 : 20;

How can I plot with 2 different y-axes?
...dd an axis label on the right-hand side. Here is an example using a little bit of made-up data:
set.seed(101)
x <- 1:10

## second data set on a very different scale
z <- runif(10, min=1000, max=10000)
