Plot a Spectral Region in Detail

Zooms into a specified wavelength range and annotates peaks.

Usage

ls_plot_region(x, min_nm, max_nm, elements = NULL, snr_threshold = 5)

Arguments

x

A ls_spectrum() or ls_dataset() object.

min_nm

Numeric. Minimum wavelength (nm).

max_nm

Numeric. Maximum wavelength (nm).

elements

Optional character vector. Element symbols to annotate. Default NULL (auto-detect top peaks).

snr_threshold

Numeric. SNR threshold for peak detection. Default 5.

Value

A ggplot2 object.

Examples

spec <- ls_simulate_spectrum(seed = 1)
ls_plot_region(spec, 380, 410)
