Label strings by wrapping across multiple lines
Uses strwrap() to split long labels across multiple lines.
label_wrap(width) wrap_format(width)
width |
Number of characters per line. |
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.
wrap_format() is retired; please use label_format() instead.
Other labels for discrete scales:
label_parse()
x <- c( "this is a long label", "this is another long label", "this a label this is even longer" ) demo_discrete(x) demo_discrete(x, labels = label_wrap(10)) demo_discrete(x, labels = label_wrap(20))
