w_length_label {ggspectra}R Documentation

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"))

w_number_label(unit.exponent = 0, format = getOption("photobiology.math",
  default = "R.expression"))

w_frequency_label(unit.exponent = 9, format = getOption("photobiology.math",
  default = "R.expression"))

Arguments

unit.exponent

integer

format

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

Value

a character string or an R expression.

Examples

w_length_label("R.expression")
w_length_label("LaTeX")
w_number_label()
