eem_absdil

According to dilution data absorbance is either multiplied by the according factor or the undiluted absorbance data is deleted. You can either specify the cor_data data table coming from <code>eem_dilcorr</code> or supply an eemlist, and the dilution data to created on the fly.

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.
