Afr_label: Absorptance axis labels

In ggspectra: Extensions to 'ggplot2' for Radiation Spectra

Absorptance axis labels

Description

Generate cps axis labels in SI units, using SI scale factors. Output can be selected as character, expression (R default devices) or LaTeX (for tikz device).

Usage

Afr_label(
  unit.exponent = 0,
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = axis_labels()[["Afr"]],
  scaled = FALSE,
  normalized = FALSE
)

Rfr_total_label(
  unit.exponent = 0,
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = NULL,
  scaled = FALSE,
  normalized = FALSE
)

Arguments

unit.exponent	integer
format	character string, "R", "R.expresion", "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).

Value

a character string or an R expression.

Examples

Afr_label()
Afr_label(-2)
Afr_label(-3)
Afr_label(format = "R.expression")
Afr_label(format = "LaTeX")
Afr_label(-2, format = "LaTeX")


Rfr_total_label()
Rfr_total_label(-2)
Rfr_total_label(-3)
Rfr_total_label(format = "R.expression")
Rfr_total_label(format = "LaTeX")
Rfr_total_label(-3, format = "LaTeX")
