%description
Perform parallel factor analysis (PARAFAC: Hitchcock, 1927)
<doi:10.1002/sapm192761164> on fluorescence excitation-emission matrices:
handle scattering signal and inner filter effect, scale the dataset, fit
the model; perform split-half validation or jack-knifing. Modified
approaches such as Whittaker interpolation, randomised split-half, and
fluorescence and scattering model estimation are also available. The
package has a low dependency footprint and has been tested on a wide range
of R versions.
