ggspectra (version 0.3.2)

raw_plot: Create a complete ggplot for raw detector-counts spectra.

Description

Plot method for spectra expressed as raw detector counts.

Usage

raw_plot(spct, w.band, range, pc.out, label.qty, span, annotations, norm,
  text.size, idfactor, ylim, na.rm, ...)

Arguments

spct

a raw_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, 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.

annotations

a character vector.

norm

numeric normalization wavelength (nm) or character string "max" for normalization at the wavelength of highest peak.

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.

ylim

numeric y axis limits,

na.rm

logical.

...

currently ignored.

Value

a ggplot object.

Details

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