Adds new feature describing the average reporter Signal/Noise ratio.

PD column Average.Reporter.SN is NA when any tags have missing values. This function adds an average reporter SN column which ignores missing values. The assumption is that the intensity values in the exprs matrix are Signal/Noise ratios, as reported by PD by default

update_average_sn(obj, sn_col = "Average.Reporter.SN")

Arguments

obj

MSnSet. Contains PSMs for TMT quantification

sn_col

string. Name of output column containing the average signal:noise.

Value

Returns an MSnSet with the average SN included as a new feature column.
