Each element in the list is an \code{ExpressionSet} } \usage{data(expressionSetList)} \details{ 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 \code{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 \code{ExpressionSetList} class. See Garber et al. (2001) for the raw data and description of the \code{stanford} study. } \source{ The experiment data package lungExpression (\url{www.bioconductor.org}) } \references{ Parmigiani et al.
