Calculate spectral derivative

This function calculates spectral derivatives using either finite approximation or the Savitzky-Golay filter method.

Usage

get.spectral.derivative(df, m = 1, method = "sgolay", get.plot = T)

Arguments

df

A DataFrame containing spectral data. Columns represent wavelengths and spectral values.

m

The order of the derivative. Default is 1.

method

The method to use for derivative calculation. Options are "finApprox" for finite approximation or "sgolay" for Savitzky-Golay filter. Default is "sgolay".

get.plot

a boolena TRUE or FALSE; if TRUE a plot will be done

Value

A DataFrame with spectral derivatives calculated based on the specified method.

Examples

if (FALSE) { # \dontrun{
# Assuming you have a DataFrame named 'spectra_df' with columns representing
# wavelengths and spectral values
derived_df <- get.spectral.derivative(spectra_df, m = 2, method = "sgolay")
} # }
