     This dataset is composed of five objects of classes
     'maigesPreRaw', 'maigesRaw' and 'maiges' containing a piece of the
     dataset that was analysed by the MAIGES (<URL:
     http://www.maiges.org/>) and published at _Cancer Research_ (see
     the reference below). In this dataset we evaluated the profiles of
     expression for 72 gastro-esophagical samples. Were used cDNA
     microarrays with slides containing 4800 spots representing
     approximately 4400 unique genes. The original dataset was composed
     from 86 samples with dye swap (what makes 172 chips). The dataset
     available here contain a subgroup of 20 samples (40 chips) and 500
     spots (486 unique genes).

     The objects available are: - 'gastro': 'maigesPreRaw' class
     containing the raw dataset. - 'gastro.raw': 'maigesRaw' class
     containing the dataset ready for filtration and normalization. -
     'gastro.raw2': same to the above, after filtration. -
     'gastro.norm': 'maiges' containing the normalized data. -
     'gastro.summ': same to the above, after summary of replicates.
