Description: Enables the analysis of spectroscopy data such as infrared
        ('IR'), Raman, and nuclear magnetic resonance ('NMR') using the
        tidy data framework from the 'tidyverse'. The 'tidyspec'
        package provides functions for data transformation,
        normalization, baseline correction, smoothing, derivatives, and
        both interactive and static visualization. It promotes
        structured, reproducible workflows for spectral data
        exploration and preprocessing. Implemented methods include
        Savitzky and Golay (1964) "Smoothing and Differentiation of
        Data by Simplified Least Squares Procedures"
