| A_plot {ggspectra} | R Documentation |
This function returns a ggplot object with an annotated plot of a source_spct object showing spectral absorbance.
A_plot(spct, w.band, range, label.qty, span, annotations, text.size, na.rm, ...)
spct |
a filter_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) |
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 |
text.size |
numeric size of text in the plot decorations. |
na.rm |
logical. |
... |
other arguments passed to absorbance() |
a ggplot 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.
