Package: OpenSpecy 1.7.1

OpenSpecy: Analyze, Process, Identify, and Share Raman and (FT)IR Spectra

Raman and (FT)IR spectral analysis tool for plastic particles and other environmental samples (Cowger et al. 2025, <doi:10.1021/acs.analchem.5c00962>). With read_any(), Open Specy provides a single function for reading individual, batch, or map spectral data files like .asp, .csv, .jdx, .spc, .spa, .0, and .zip. process_spec() simplifies processing spectra, including smoothing, baseline correction, range restriction and flattening, intensity conversions, wavenumber alignment, and min-max normalization. Spectra can be identified in batch using an onboard reference library using match_spec(). A bundled Shiny app is available via run_app() or online at <https://www.openanalysis.org/openspecy/>.
