O_plot {ggspectra}R Documentation

Plot an object spectrum

Description

This function returns a ggplot object with an annotated plot of spectral transmittance, absorptance and reflectance.

Usage

O_plot(spct, w.band, range, pc.out, label.qty, span, annotations, stacked,
  text.size, na.rm, ...)

Arguments

spct

an object_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

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

stacked

logical

text.size

numeric size of text in the plot decorations.

na.rm

logical.

...

other arguments passed to reflectance()

Value

a ggplot object.

Note

Note that scales are expanded so as to make space for the annotations. The object returned is a ggplot object, and can be further manipulated.
