Finds optimal scattering cut widths based on EEM set

Takes a group of EEMs and uses peak picking to determine how wide the cut should be for each scattering line (does not work for 2nd order raman). Uses the excitation at 280nm and finds the start and end of the peak. If the function can't find one, it will default to NA for that sample. Median of the peak widths is reported for use in the 'remove_scattering' function. Should be performed on data that is untransformed besides a blank subtraction.

Usage

find_cut_width(eem, type = "rayleigh", order = 1)

Arguments

eem

an object of class eemlist

type

a string, either "raman" or "rayleigh"

order

an integer number, either 1 (first order) or 2 (second order)
