Arguments

x	A numeric vector
accuracy	A number to round to. Use (e.g.) 0.01 to 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.
scale	A scaling factor: x will be multiplied by scale before formating. This is useful if the underlying data is very small or very large.
units	A single string indcating the unit system to use. Should be either "SI" or "IP"
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 FALSE, values are right-justified to a common width (see base::format()).
parse	If TRUE, the labels will be parsed into expressions and displayed as described in ?plotmath. Default: FALSE.
...	Other arguments passed on to base::format().

Value

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.

Examples

demo_scale(10:50, labels = label_drybulb(units = "SI", parse = TRUE))
demo_scale(10:50, labels = label_drybulb(units = "IP", parse = TRUE))

demo_scale(10:20, labels = label_humratio(scale = 0.001, units = "SI", parse = TRUE))
demo_scale(10:20, labels = label_humratio(scale = 0.007, units = "IP", parse = TRUE))

demo_scale(10:50, labels = label_relhum(units = "SI"))
demo_scale(10:50, labels = label_relhum(units = "IP"))

demo_scale(10:50, labels = label_wetbulb(units = "SI", parse = TRUE))
demo_scale(10:50, labels = label_wetbulb(units = "IP", parse = TRUE))

demo_scale(10:50, labels = label_specvol(units = "SI", parse = TRUE))
demo_scale(10:50, labels = label_specvol(units = "IP", parse = TRUE))

demo_scale(10:50, labels = label_vappres(units = "SI"))
demo_scale(10:50, labels = label_vappres(units = "IP"))

demo_scale(seq(1000, 2000), labels = label_enthalpy(units = "SI", parse = TRUE))
demo_scale(seq(1000, 2000), labels = label_enthalpy(units = "IP", parse = TRUE))
