expandProbesets: ## expand featureNames of an ExpressionSet that are 2+...

Description Usage Arguments Author(s)

Description

If a single probeset is collapsed to multiple ids, for example ZNRF2///MIR550-1, then this will create an ExpressionSet with single ids. ZNRF2 and MIR550-1 will be two identical rows in the exprs(). Useful for accessing genes. If ids are not unique, the first instance is chosen. Priority is given however to probesets with single ids (i.e. if there is a "ZNRF2" and a "ZNRF2///MIR550-1" probe, the uncollapsed ExpressionSet will have the first probe ("ZNRF2") and the second ("MIR550-1"), not the second probe twice). Function by Markus Riester.
