`label_parse()`

produces expression from strings by parsing them;
`label_math()`

constructs expressions by replacing the pronoun `.x`

with each string.

label_parse() label_math(expr = 10^.x, format = force) parse_format() math_format(expr = 10^.x, format = force)

expr | expression to use |
---|---|

format | another format function to apply prior to mathematical transformation - this makes it easier to use floating point numbers in mathematical expressions. |

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.

`parse_format()`

and `math_format()`

was retired; please use
`label_parse()`

and `label_math()`

instead.
