%description
Pre-processing and polymer identification of Raman spectra of plastics.
Pre-processing includes normalisation functions, peak identification based
on local maxima, smoothing process and removal of spectral region of no
interest. Polymer identification can be performed using Pearson
correlation coefficient or Euclidean distance (Renner et al. (2019),
<doi:10.1016/j.trac.2018.12.004>), and the comparison can be done with a
user-defined database or with the database already implemented in the
package, which currently includes 356 spectra, with several spectra of
plastic colorants.
