plot_spec_regions: Plot polygons for spectral regions

In annakat/casper_defunct: Class and methods for hyperspectral data

Description

spec_regions = cbind("VIS" = c(begin = 400, end = 700), "NIR" = c(begin = 800, end = 1300), "SWIR1" = c(begin = 1550, end = 1800), "SWIR2" = c(begin = 2000, end = 2400))

Usage

plot_spec_regions(spec, regions, col = rgb(0.7, 0.7, 0.7, 0.3),
  border = FALSE, add = FALSE, names = TRUE, ...)

Arguments

spec	spectra object
regions	matrix with spectral regions in columns and only two rows named "begin" and "end". Values are the wavelengths where a spectral regions begins and ends. See details for an example
col	color for regions. single value or vector of length ncol(regions)
border	color for region borders. Defaults to FALSE (no border)
add	boolean. If TRUE (default) adds polygons to current plot. Otherwise a new plot is created **without** any spectra.
names	boolean. add region column names on top of the polygons?
...	additional parameters passed to polygon()

Value

nothing. called for its side effect
