StabilityUnion-class: "StabilityUnion"

In GeneSelector: Stability and Aggregation of ranked gene lists

Description

An object returned from a call to GetStabilityUnion.

Slots

union:

A numeric vector of scores derived from union counts, normalized such that 1 is the maximum attainable value. The entries correspond to the positions in the list such that the i-th entry contains the score derived from the union count up to position i.

unionscore:

A numeric vector of union scores, arranged analogously to union.

noinformation:

A list containing an approximation to the expected union count and -score if noinformation in GetStabilityUnion has been set to a positive integer. Otherwise, the list is empty.

decay

The decay scheme used for the weights, s. GetStabilityUnion.

Methods

show

Use show(object) for brief information.

plot

plot(object, frac=1/50, ...) produces a graphical display of the union count (upper panel) and union score (lower panel) for increasing list position, ranging from 1 to frac*number of genes. The ... argument may be used to modify graphical options.
