In ggspectra: Extensions to 'ggplot2' for Radiation Spectra

Absorbance y-scale

Description

Scale y continuous with defaults suitable for spectral absorbance.

Usage

scale_y_A_continuous(
  unit.exponent = 0,
  name = A_label(unit.exponent = unit.exponent, format = format, label.text = label.text,
    scaled = scaled, normalized = ifelse(is.numeric(normalized), round(normalized, 1),
    unique(normalized)), axis.symbols = axis.symbols, Tfr.type = Tfr.type),
  labels = SI_pl_format(exponent = unit.exponent),
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = NULL,
  scaled = FALSE,
  normalized = FALSE,
  axis.symbols = getOption("ggspectra.axis.symbols", default = TRUE),
  Tfr.type,
  ...
)

scale_y_A_internal_continuous(
  unit.exponent = 0,
  name = A_label(unit.exponent = unit.exponent, format = format, label.text = label.text,
    scaled = scaled, normalized = ifelse(is.numeric(normalized), round(normalized, 1),
    unique(normalized)), axis.symbols = axis.symbols, Tfr.type = "internal"),
  labels = SI_pl_format(exponent = unit.exponent),
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = NULL,
  scaled = FALSE,
  normalized = FALSE,
  axis.symbols = getOption("ggspectra.axis.symbols", default = TRUE),
  ...
)

scale_y_A_total_continuous(
  unit.exponent = 0,
  name = A_label(unit.exponent = unit.exponent, format = format, label.text = label.text,
    scaled = scaled, normalized = ifelse(is.numeric(normalized), round(normalized, 1),
    unique(normalized)), axis.symbols = axis.symbols, Tfr.type = "total"),
  labels = SI_pl_format(exponent = unit.exponent),
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = NULL,
  scaled = FALSE,
  normalized = FALSE,
  axis.symbols = getOption("ggspectra.axis.symbols", default = TRUE),
  ...
)

Arguments

unit.exponent	integer
name	The name of the scale, used for the axis-label.
labels	The tick labels or a function to generate them.
format	character string, "R", "R.expression", "R.character", or "LaTeX".
label.text	character Textual portion of the labels.
scaled	logical If TRUE relative units are assumed.
normalized	logical (FALSE) or numeric Normalization wavelength in manometers (nm).
axis.symbols	logical If TRUE symbols of the quantities are added to the name. Supported only by format = "R.expression".
Tfr.type	character, either "total" or "internal".
...	other named arguments passed to scale_y_continuous

Note

This function only alters two default arguments, please, see documentation for scale_continuous
