eem_fluorescence_index: Calculate the fluorescence index (FI)

Description

Calculate the fluorescence index (FI)

Usage

eem_fluorescence_index(eem, verbose = TRUE)

Arguments

eem

An object of class eem

verbose

Logical determining if additional messages should be printed.

Value

• A data frame containing fluorescence index (FI) for each eem.

Interpolation

Different excitation and emission wavelenghts are often used to measure EEMs. Hence, it is possible to have mismatchs bewteen measured wavelengths and wavelenghts 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.
