eempf_rescaleBC

B and C modes (emission and excitation wavelengths) are rescaled to RMS of value newscale. This is compensated in A mode (sample loadings).

This is a user-friendly way to run a parallel factor (PARAFAC) analysis (Harshman, 1971) <doi:10.1121/1.1977523> on excitation emission matrix (EEM) data from dissolved organic matter (DOM) samples (Murphy et al., 2013) <doi:10.1039/c3ay41160e>. The analysis includes profound methods for model validation. Some additional functions allow the calculation of absorbance slope parameters and create beautiful plots.

eempf_rescaleBC function

<dl><dt>pfmodel</dt>
<dd>object of class parafac</dd>
<dt>newscale</dt>
<dd>If (default) newscale = "Fmax", each component will be scaled so the maximum of each component is 1. It is also possible to set a desired root mean-square for each column of the rescaled mode. Can input a scalar or a vector with length equal to the number of factors for the given mode.</dd></dl>
