     Object of class 'ExpressionSetList' containing three studies. Each
     element in the list is an 'ExpressionSet'

_D_e_t_a_i_l_s:

     Parmigiani et al. (2004) performed a cross-study analysis of three
     lung cancer studies.  The studies used in this analysis were
     merged by UniGene identifiers to obtain a set of 3,171 gene.  The
     R experiment data package 'lungExpression' that was developed to
     facilitate the reproducibility of this analysis contains the three
     studies as ExpressionSets.  Here, we take a random sample of 500
     features from one study (the "stanford" study), and split this
     study into three artificial studies that each contain 4 squamous
     carcinomas and 3 adenocarcinomas.  The three artificial studies
     are then used to create an instance of the 'ExpressionSetList'
     class.

     See Garber et al. (2001) for the raw data and description of the
     'stanford' study.
