EMSC_model

Sets up an EMSC model to be applied to one or more set of spectra.

Background correction of spectral like data. Handles variations in
scaling, polynomial baselines, interferents, constituents and replicate variation.
Parameters for corrections are stored for further analysis, and spectra are corrected
accordingly.

EMSC_model function

<dl><dt>x</dt>
<dd><code>numeric</code> vector containing abcissas of spectra to be corrected or matrix to be 
corrected with/without names colnames.</dd>
<dt>reference</dt>
<dd><code>numeric</code> vector containing the reference spectrum.</dd>
<dt>degree</dt>
<dd><code>integer</code> giving the polynomial degree of the baseline; 0 or higher, default = 2.</dd>
<dt>interferent</dt>
<dd><code>numeric</code> vector containing a spectral component to remove.</dd>
<dt>constituent</dt>
<dd><code>numeric</code> vector containing a spectral component to include.</dd>
<dt>weights</dt>
<dd><code>numeric</code> vector of abcissas weights.</dd>
<dt>replicates</dt>
<dd>optional <code>vector</code> which identifies replicates. Default = NULL,
