O_plot: Create a complete ggplot for a object spectrum.

In aphalo/ggspectra: Extensions to 'ggplot2' for Radiation Spectra

Create a complete ggplot for a object spectrum.

Description

This function returns a ggplot object with an annotated plot of an object_spct displaying spectral transmittance, absorptance and reflectance.

Usage

O_plot(
  spct,
  w.band,
  range,
  pc.out,
  label.qty,
  span,
  wls.target,
  annotations,
  geom,
  stacked,
  text.size,
  chroma.type,
  facets,
  na.rm,
  ylim,
  ...
)

Arguments

spct	an object_spct object.
w.band	list of waveband objects.
range	an R object on which range() returns a vector of length 2, with min annd max wavelengths (nm).
pc.out	logical, if TRUE use percents instead of fraction of one.
label.qty	character string giving the type of summary quantity to use for labels.
span	a peak is defined as an element in a sequence which is greater than all other elements within a window of width span centered at that element.
wls.target	numeric vector indicating the spectral quantity values for which wavelengths are to be searched and interpolated if need. The character strings "half.maximum" and "half.range" are also accepted as arguments. A list with numeric and/or character values is also accepted.
annotations	a character vector.
geom	character.
stacked	logical.
text.size	numeric size of text in the plot decorations.
chroma.type	character one of "CMF" (color matching function) or "CC" (color coordinates) or a chroma_spct object.
na.rm	logical.
ylim	numeric y axis limits,
...	currently ignored.

Value

a ggplot object.

Note

Note that scales are expanded so as to make space for the annotations. The object returned is a ggplot object, and can be further manipulated.
