generic_plot: Create a complete ggplot for generic spectral data.

Description

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

Usage

generic_plot(
  spct,
  y.name,
  ymin.name,
  ymax.name,
  ylab,
  w.band,
  range,
  label.qty,
  span,
  wls.target,
  annotations,
  text.size,
  idfactor,
  facets,
  ylim,
  na.rm
)

Value

a ggplot object.

Arguments

spct: a generic_spct object
y.name, ymin.name, ymax.name: character Names of the columns to be mapped to the y aesthetic.
ylab: character or expression The y-axis label.
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)
label.qty: character string giving the type of summary quantity to use for labels, one of "mean", "total", "contribution", and "relative".
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
text.size: numeric size of text in the plot decorations.
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.
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.
