eem_fluorescence_index {eemR} | R Documentation |
Calculate the fluorescence index (FI)
Description
Calculate the fluorescence index (FI)
Usage
eem_fluorescence_index(eem, verbose = TRUE)
Arguments
eem |
An object of class |
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.
