label_scientific {scales} | R Documentation |
Label numbers with scientific notation (e.g. 1e05, 1.5e-02)
label_scientific(digits = 3, scale = 1, prefix = "", suffix = "", decimal.mark = ".", trim = TRUE, ...) scientific_format(digits = 3, scale = 1, prefix = "", suffix = "", decimal.mark = ".", trim = TRUE, ...) scientific(x, digits = 3, scale = 1, prefix = "", suffix = "", decimal.mark = ".", trim = TRUE, ...)
digits |
Number of digits to show before exponent. |
scale |
A scaling factor: |
prefix, suffix |
Symbols to display before and after value. |
decimal.mark |
The character to be used to indicate the numeric decimal point. |
trim |
Logical, if |
... |
Other arguments passed on to |
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.
scientific_format()
and scientific()
are retired; please use
label_scientific()
.
