)a ggplot object.
a raw_spct object.
list of waveband objects.
an R object on which range() returns a vector of length 2, with min annd max wavelengths (nm).
logical, if TRUE use percents instead of fraction of one.
character string giving the type of summary quantity to use for labels, one of "mean", "total", "contribution", and "relative".
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.
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.
a character vector.
character The name of a ggplot geometry, currently only
"area", "spct" and "line". The default NULL
selects between them based on stacked.
numeric size of text in the plot decorations.
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.
logical or integer Indicating if facets are to be created for
the levels of idfactor when spct contain multiple spectra in
long form.
numeric y axis limits,
logical.
This function returns a ggplot object with an annotated plot of a raw_spct object.
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. When spct has more than one column with spectral data, each of these columns is normalized individually.
