Added Raman/SERS spectral preprocessing functions:
raman_crop_spectra(), raman_despike(),
airPLS_fast_dataset(), raman_normalize() and
raman_sgolay_derivative().
Added Raman/SERS peak-analysis functions:
raman_find_peaks(), raman_align_peaks() and
raman_normalize_peak_features().
Added optional Fourier and Haar wavelet feature extraction
through raman_transform_fourier() and
raman_transform_wavelet().
Added interactive PCA 3D score plots with
pca_scoresplot3D() and improved support for non-consecutive
principal-component selections in 3D PCA visualizations.
Improved input validation, documentation and reproducible examples for Raman/SERS and PCA workflows.
Improved compatibility of PCA 3D group colouring for metadata factors with unused levels. # specmine 3.1.8
Fixed malformed roxygen example blocks.
Added and improved \value{} documentation in
.Rd files.
Removed commented example code and improved example robustness for checks.
Improved documentation consistency.
