COBRAData, COBRAPerformance or COBRAPlot
objectsFunctions to subset COBRAData, COBRAPerformance or
COBRAPlot objects. COBRAData objects are subset by features
(rows), while COBRAPerformance and COBRAPlot objects are subset
by methods (columns). Numeric indices are not allowed, since not all slots
may be arranged in the same order.
