Label percentages (2.5%, 50%, etc)
label_percent( accuracy = NULL, scale = 100, prefix = "", suffix = "%", big.mark = " ", decimal.mark = ".", trim = TRUE, ... )
A number to round to. Use (e.g.)
0.01to show 2 decimal places of precision. If
NULL, the default, uses a heuristic that should ensure breaks have the minimum number of digits needed to show the difference between adjacent values.
Applied to rescaled data.
A scaling factor:
xwill be multiplied by
scalebefore formatting. This is useful if the underlying data is very small or very large.
Additional text to display before the number. The suffix is applied to absolute value before
style_negativeare processed so that
prefix = "$"will yield (e.g.)
Additional text to display after the number.
Character used between every 3 digits to separate thousands.
The character to be used to indicate the numeric decimal point.
FALSE, values are right-justified to a common width (see
Other arguments passed on to
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.
