RMAT (version 3.22.0)

tilingSet: This object contains an ExpressionSet

Description

This object contains an ExpressionSet and has the following additional slots: genomeName, featureSequence, featurePosition, featureChromosome, featureCopyNumber

Details

Tiling set objects can also be combined using the rbind methods. This is particularly useful when several arrays span a genome/chromosome.
