[BioC] CAMERA for non-directional gene sets

[Simon de Bernard]

The publication for CAMERA (http://nar.oxfordjournals.org/content/early/2012/05/24/nar.gks461.full) mentions using the average absolute-logFC as a statistics for "non-directional" gene sets.

This would seem like the appropriate approach for gene sets from e.g. the GO database.

However I was unable to find how to use anything other than logFC or its rank from the camera documentation in limma.

Have I missed something?

Thanking you in advance,

Best regards,

Simon.
