R_plot: Create a complete ggplot for a reflector spectrum.

Description

This function returns a ggplot object with an annotated plot of a reflector_spct reflectance.

Usage

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

Value

a ggplot object.

Arguments

spct: a filter_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.
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.
idfactor: character Name of an index column in data holding a factor with each spectrum in a long-form multispectrum object corresponding to a distinct spectrum. If idfactor=NULL the name of the factor is retrieved from metadata or if no metadata found, the default "spct.idx" is tried. If idfactor=NA no aesthetic is mapped to the spectra and the user needs to use 'ggplot2' functions to manually map an aesthetic or use facets for the spectra.
facets: logical or integer Indicating if facets are to be created for the levels of idfactor when spct contain multiple spectra in long form.
ylim: numeric y axis limits,
na.rm: logical.
...: currently ignored.
