Label psychrometric scale breaks

Source: R/labels.R
label.Rd

Format numbers as main variables on the psychrometric chart.

Usage

label_drybulb(
  accuracy = NULL,
  scale = 1,
  units,
  big.mark = ",",
  decimal.mark = ".",
  trim = TRUE,
  parse = FALSE,
  ...
)

label_humratio(
  accuracy = NULL,
  scale = 1,
  units,
  big.mark = ",",
  decimal.mark = ".",
  trim = TRUE,
  parse = FALSE,
  ...
)

label_relhum(
  accuracy = NULL,
  scale = 1,
  units,
  big.mark = ",",
  decimal.mark = ".",
  trim = TRUE,
  parse = FALSE,
  ...
)

label_wetbulb(
  accuracy = NULL,
  scale = 1,
  units,
  big.mark = ",",
  decimal.mark = ".",
  trim = TRUE,
  parse = FALSE,
  ...
)

label_vappres(
  accuracy = NULL,
  scale = 1,
  units,
  big.mark = ",",
  decimal.mark = ".",
  trim = TRUE,
  parse = FALSE,
  ...
)

label_specvol(
  accuracy = NULL,
  scale = 1,
  units,
  big.mark = ",",
  decimal.mark = ".",
  trim = TRUE,
  parse = FALSE,
  ...
)

label_enthalpy(
  accuracy = NULL,
  scale = 1,
  units,
  big.mark = ",",
  decimal.mark = ".",
  trim = TRUE,
  parse = FALSE,
  ...
)

Arguments

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 formatting. This is useful if the underlying data is very small or very large.

units

A single string indicating the unit system to use. Should be either "SI" or "IP"

big.mark

Character used between every 3 digits to separate thousands. The default (NULL) retrieves the setting from the number options.

decimal.mark

The character to be used to indicate the numeric decimal point. The default (NULL) retrieves the setting from the number options.

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

A labelling function that formats numeric breaks.

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(units = "SI", parse = TRUE))

demo_scale(70:140, labels = label_humratio(units = "IP", parse = TRUE))


demo_scale(seq(0.1, 0.5, by = 0.1), labels = label_relhum(units = "SI"))

demo_scale(seq(0.1, 0.5, by = 0.1), 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))
