spec_diff {tidyspec}R Documentation

Apply Differentiation to Spectral Data

Description

This function applies numerical differentiation to spectral data, allowing for the calculation of the first or higher-order differences.

Usage

spec_diff(.data, wn_col = NULL, degree = 1)

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"'.

degree

A numeric value specifying the degree of differentiation. If 'degree' is 0, the original data is returned without any changes.

Value

A 'tibble' with the differentiated spectral data, containing the wavelength column and the differentiated numeric columns. If 'degree' is 0, the original data is returned.
