R: Plot method for spectra expressed as raw detector counts.

raw_plot {ggspectra} | R Documentation

## Plot method for spectra expressed as raw detector counts.

### Description

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

### Usage

    raw_plot(spct, w.band, range, pc.out, label.qty, span, annotations, norm,
      text.size, 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.
`na.rm` | logical.
`...` | other arguments

### 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. When spct has more than one column with spectral data, each of these columns is normalized individually.
