ggspectra (version 0.3.13)

O_plot: 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
)

Value

a ggplot object.

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,
