Use label_number()
force decimal display of numbers (i.e. don't use
scientific notation). label_comma()
is a special case
that inserts a comma every three digits.
label_number( accuracy = NULL, scale = 1, prefix = "", suffix = "", big.mark = " ", decimal.mark = ".", trim = TRUE, ... ) label_comma( accuracy = NULL, scale = 1, prefix = "", suffix = "", big.mark = ",", decimal.mark = ".", trim = TRUE, digits, ... ) comma( x, accuracy = NULL, scale = 1, prefix = "", suffix = "", big.mark = ",", decimal.mark = ".", trim = TRUE, digits, ... ) number_format( accuracy = NULL, scale = 1, prefix = "", suffix = "", big.mark = " ", decimal.mark = ".", trim = TRUE, ... ) comma_format( accuracy = NULL, scale = 1, prefix = "", suffix = "", big.mark = ",", decimal.mark = ".", trim = TRUE, digits, ... )
accuracy | A number to round to. Use (e.g.) Applied to rescaled data. |
---|---|
scale | A scaling factor: |
prefix, suffix | Symbols to display before and after value. |
big.mark | Character used between every 3 digits to separate thousands. |
decimal.mark | The character to be used to indicate the numeric decimal point. |
trim | Logical, if |
... | Other arguments passed on to |
digits | Deprecated, use |
x | A numeric vector to format. |
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.
number_format()
, comma_format()
, and comma()
are retired; please use
label_number()
and label_comma()
instead.
