TopnPeptides {DAPAR} | R Documentation |
This function computes the intensity of proteins as the sum of the intensities of their n best peptides.
TopnPeptides(matAdj, expr, n)
matAdj |
An adjacency matrix in which lines and columns correspond respectively to peptides and proteins. |
expr |
A matrix of intensities of peptides |
n |
The maximum number of peptides used to aggregate a protein. |
A matrix of intensities of proteins
