Apply Savitzky-Golay Smoothing to Spectral Data

Description

This function applies Savitzky-Golay smoothing to numeric spectral data using a specified window size, polynomial order, and differentiation degree, while preserving the wavelength column.

Usage

spec_smooth_sga(.data, wn_col = NULL, window = 15, forder = 4, degree = 0)

Arguments

.data

A 'data.frame' or 'tibble' containing spectral data.

wn_col

A character string specifying the column name for the wavelength data. Default is '"Wn"'.

window

A numeric value specifying the window size for the Savitzky-Golay smoothing. Default is 15.

forder

A numeric value specifying the polynomial order for smoothing. Default is 4.

degree

A numeric value specifying the degree of differentiation. Default is 0 (no differentiation).

Value

A 'tibble' with the smoothed spectral data, containing the wavelength column and the smoothed numeric columns.
