filterMaxMarkers: Removes class/annotation information from a matrix of candidate
markers that appear in the fData.
Description
Removes annotation information that contain more that a
certain number/percentage of proteins
Usage
filterMaxMarkers(object, n, p = 0.2, fcol = "GOAnnotations", verbose = TRUE)
Arguments
object
An instance of class MSnSet.
n
Maximum number of proteins allowed per class/information
term.
p
Maximum percentage of proteins per column. Default is 0.2
i.e. remove columns that have information for greater than 20
of the total number of proteins in the dataset (note: this is useful
for example, if information is GO terms, for removing very general
and uninformative terms).

GOAnnotations.
verbose
Number of marker candidates retained after filtering.
