In ggspectra: Extensions to 'ggplot2' for Radiation Spectra

Reflectance y-scale

Description

Scale y continuous with defaults suitable for spectral reflectance.

Usage

scale_y_Rfr_continuous(
  unit.exponent = ifelse(pc.out, -2, 0),
  name = Rfr_label(unit.exponent = unit.exponent, format = format, label.text =
    label.text, scaled = scaled, normalized = ifelse(is.numeric(normalized),
    round(normalized, 1), unique(normalized)), axis.symbols = axis.symbols, Rfr.type =
    Rfr.type),
  labels = SI_pl_format(exponent = unit.exponent),
  limits = c(0, 1),
  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,
  ...
)

    label.text, scaled = scaled, normalized = ifelse(is.numeric(normalized),
    round(normalized, 1), unique(normalized)), axis.symbols = axis.symbols, Rfr.type =
    "total"),
  labels = SI_pl_format(exponent = unit.exponent),
  limits = c(0, 1),
  format = getOption("photobiology.math", default = "R.expression"),

Arguments

unit.exponent	integer
name	The name of the scale, used for the axis-label.
labels	The tick labels or a function to generate them.
limits	One of NULL for default based on data range, a numeric vector of length two (NA allowed) or a function that accepts the data-based limits as argument and returns new limits.
format	character string, "R", "R.expression", "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 "spcular".
...	other named arguments passed to scale_y_continuous

Note

This function only alters two default arguments, please, see documentation for scale_continuous
