s.e.irrad_label: spectral irradiance axis labels

In ggspectra: Extensions to 'ggplot2' for Radiation Spectra

spectral irradiance axis labels

Description

Generate 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

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

s.q.irrad_label(
  unit.exponent = ifelse(normalized, 0, -6),
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = axis_labels()[["s.q.irrad"]],
  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

counts_label()
counts_label("R.expression")
counts_label("LaTeX")
