Plot Spectral Profiles

Displays spectral profiles from an HSI cube. Can show mean spectrum, random pixel spectra, or spectra from specific pixel locations.

Usage

hs_plot_spectra(cube, pixels = "mean", n = 100L, show_sd = TRUE)

Arguments

cube

An hsi_cube object.

pixels

Character or data.frame. "mean" for spatial mean, "random" for random pixel sample, or a data.frame with columns x and y. Default "mean".

n

Integer. Number of random spectra if pixels = "random". Default 100.

show_sd

Logical. Show mean +/- SD ribbon. Default TRUE when pixels = "mean".

Value

A ggplot2::ggplot object.

Examples

cube <- hs_example_cube()
hs_plot_spectra(cube)
