accuracy |
A number to round to. Use (e.g.) Applied to rescaled data. |
scale |
A scaling factor: |
prefix |
Additional text to display before the number. The suffix is
applied to absolute value before |
suffix |
Additional text to display after the number. |
big.mark |

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.
Other labels for continuous scales:
label_bytes()
,
label_currency()
,
label_number_auto()
,
label_number_si()
,
label_ordinal()
,
label_parse()
,
label_pvalue()
,
label_scientific()

# Use prefix and suffix to create your own variants

decimal.mark = ",",
suffix = " %"
