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.
