project_opls

Projects new spectra onto a PLS space based on a model generated by either by <code>opls</code> or the <code>opls2</code> functions.
For internal use only!.

Functions for dissimilarity analysis and memory-based learning
(MBL, a.k.a local modeling) in complex spectral data sets.
Most of these functions are based on the methods presented in
Ramirez-Lopez et al. (2013) <doi:10.1016/j.geoderma.2012.12.014>.
