Uses strwrap() to split long labels across multiple lines.
Value
All label_() functions return a "labelling" function, i.e. a function that
takes a vector x and returns a character vector of length(x) giving a
label for each input value.
Labelling functions are designed to be used with the labels argument of
ggplot2 scales. The examples demonstrate their use with x scales, but
they work similarly for all scales, including those that generate legends
rather than axes.

Examples
x <- c(
"this is a long label",
"this is another long label",
"this a label this is even longer"
)
demo_discrete(x)
#> scale_x_discrete()
demo_discrete(x, labels = label_wrap(10))
#> scale_x_discrete(labels = label_wrap(10))
demo_discrete(x, labels = label_wrap(20))
#> scale_x_discrete(labels = label_wrap(20))
