aggregateTopn {DAPAR} | R Documentation |
This function computes the intensity of proteins as the sum of the intensities of their n best peptides.
aggregateTopn(obj.pep, X, method = "Mean", n = 10)
obj.pep |
A matrix of intensities of peptides |
X |
An adjacency matrix in which lines and columns correspond respectively to peptides and proteins. |
method |
xxx |
n |
The maximum number of peptides used to aggregate a protein. |
