Normalisation based on an External Factor

This function utilises an array of dilution coefficients acquired externally to normalise the spectra.

xfNorm(X, xfactor)

Arguments

X	A numerical matrix with rows being the spectra and columns being the chemical shift variables
xfactor	A numerical array of values that correspond to the dilution coefficients of the spectra. Must be row-matched to the provided X matrix.

Value

This function returns a list with:

1. The normalised X matrix in the first list element, and

2. A numerical array of the corresponding dilution factors in the second.

• Following the example below will extract the results quickly and easily.

Details

xfNorm() works by dividing all values within a spectrum by the value of its external factor.
