w_length_label: Wave- axis labels

Description

Generate wavelength, wavenumber and wave frequency 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

w_length_label(
  unit.exponent = -9,
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = axis_labels()[["w.length"]]
)
w_number_label(
  unit.exponent = 0,
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = axis_labels()[["w.number"]]
)
w_frequency_label(
  unit.exponent = 9,
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = axis_labels()[["freq"]]
)

Value

a character string or an R expression.

Arguments

unit.exponent

integer

format

character string, "R", "R.expresion", "R.character", or "LaTeX".

label.text

character Textual portion of the labels.
