T_plot: Create a complete ggplot for a filter spectrum.

In ggspectra: Extensions to 'ggplot2' for Radiation Spectra

Create a complete ggplot for a filter spectrum.

Description

This function returns a ggplot object with an annotated plot of a filter_spct object showing transmittance.

Usage

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

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.
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 objects, and can be further manipulated.
