maxLFQ | R Documentation |
Estimates protein abundances by aiming to maintain the fragment intensity ratios between samples.
maxLFQ(X)
X |
A matrix of ion intensities in log2 space. Columns are samples and rows are fragment ions. |
A list of two components is returned
estimate |
A vector with length equal to the number of columns of the input containing the protein abundances in log2 space. |
annotation |
An empty string if all quantified samples are connected. Otherwise, a string of membership of the connected components is returned. |
