StabilityUnion-class {GeneSelector} | R Documentation

## "StabilityUnion"

### 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.
