Description Objects from the Class Slots Methods References Examples
Tests whether the connectivity scores for a set of important genes differ between two networks.
Objects can be created by calls of the form new("resultsClassTest", ...)
.
p.value
:Object of class "numeric"
; the p-value for the significance test.
delta
:Object of class "numeric"
; the test statistic for the significance test.
class.genes
:Object of class "character"
; the list of important genes.
signature(object = "resultsClassTest")
: returns the p-value, test statistic, and the class of genes for a test for differential connectivity of the class of genes.
signature(object = "resultsClassTest")
: summarizes the test by outputing the class of important genes, the value of the test statistic, and its p-value.
