)a cps_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
numeric normalization wavelength (nm) or character string "max" for normalization at the wavelength of highest peak.
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.
numeric y axis limits,
logical.
currently ignored.
