Rfr_label: Reflectance axis labels

Description

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

Usage

Rfr_label(
  unit.exponent = ifelse(pc.out, -2, 0),
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = NULL,
  scaled = FALSE,
  normalized = FALSE,
  axis.symbols = getOption("ggspectra.axis.symbols", default = TRUE),
  pc.out = getOption("ggspectra.pc.out", default = FALSE),
  Rfr.type
)
Rfr_specular_label(
  unit.exponent = ifelse(pc.out, -2, 0),
  format = getOption("photobiology.math", default = "R.expression"),
  label.text = NULL,
  scaled = FALSE,
  normalized = FALSE,
  axis.symbols = getOption("ggspectra.axis.symbols", default = TRUE),
  pc.out = getOption("ggspectra.pc.out", default = FALSE)
)

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.

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".

pc.out

logical, if TRUE use percent as default instead of fraction of one.

Rfr.type

character, either "total" or "specular".

Examples

Rfr_label(Rfr.type = "specular")
Rfr_label(Rfr.type = "total")


Rfr_specular_label()
Rfr_specular_label(axis.symbols = FALSE)
Rfr_specular_label(-2)
Rfr_specular_label(-3)
Rfr_specular_label(format = "R.expression")
Rfr_specular_label(format = "LaTeX")
Rfr_specular_label(-3, format = "LaTeX")
