pairwise.filter {simpleaffy} | R Documentation |
Given the results of a pairwise.comparison, filter the resulting gene list on expression level, PMA calls (if available), fold change and t-test statistic
object |
a 'PairComp' object |
eset |
an 'exprSet' object used to filter by intensity |
min.exp |
Filter genes using a minimum expression cut off |
min.exp.no |
A gene must have an expression intensity greater than 'min.exp' in at least this number of chips |
min.present.no |
A gene must be called present on at least this number of chips |
fc |
A gene must show a log2 fold change greater than this to be called significant |
tt |
A gene must be changing with a p-score less than this to be called significant |
A 'PairComp' object filtered to contain only the genes that pass the specified filter parameters.
