42 milk (should be fish oil) samples with 3 replicates each constitute a Raman data set of 126 samples over 3471 Raman shifts. There is a large fluorescence signal in the spectra that needs to be removed before any data analysis can be performed.
data(milk)A data.frame consisting of three parts. The estimated Iodine concentrations
of the milk samples, Raman spectra (matrix) and a replicate vector.
