Description
Calculate the fluorescence index (FI)
Usage
1
eem_fluorescence_index(eem, verbose = TRUE)
Arguments
eem
An object of class eemlist.
verbose
Logical determining if additional messages should be printed.
Value
An object of class eemlist.
A data frame containing fluorescence index (FI) for each eem.
Interpolation
Different excitation and emission wavelengths are often used to measure
EEMs. Hence, it is possible to have mismatchs between measured wavelengths
and wavelengths used to calculate specific metrics. In these circumstances,
EEMs are interpolated using the interp2 function from the
parcma library. A message warning the user will be prompted if data
interpolation is performed.
