sample_plot: Plot hyperspectral cube samples

In AlexCast/surfspec: PAE tools for imaging spectroscopy

Plot hyperspectral cube samples

Description

This function provides a easy interface for simple plots.

Usage

sample_plot(cube, sample, id, summary = TRUE, loc = mean, disp = sd, ylab, ...)

Arguments

cube	The hyperspectral cube returned by the function cube_read from which the sample were taken.
sample	An object returned be the function cube_sample.
id	Optional specification of the samples to be used. Default to use all samples.
summary	Logical. Should every pixel be plotted or descriptive statistics?
loc	If summary is TRUE, the location function to be used. Defaults to mean.
disp	If summary is TRUE, the dispersion function to be used. Defaults to sd.
...	Arguments to be passed to cube_rgb (e.g., log = T) and descriptive statistics functions (e.g., na.rm = TRUE).

Details

This function provides a simple visualization for point (or circle) or line samples taken with the function cube_sample. The cube_rgb is called to show the spatial position of the samples and a second plot is called to plot the samples per wavelength. Note that by default, the ylab will be expression(rho~(unitless)) if not provided.

The location and dispersion metric functions should return a single value per sample. Read the documentation of sample_stat.
