This function strips out probes that are not shared by all given data sets, and orders the remaining common probes using the same order in all sets.
keepCommonProbes(multiExpr, orderBy = 1)
expression data in the multi-set format (see checkSets
). A vector of
lists, one per set. Each set must contain a component data
that contains the expression data, with
rows corresponding to samples and columns to genes or probes.
index of the set by which probes are to be ordered.
