data:sample.ExpressionSet      package:Biobase      R Documentation

Dataset of class 'ExpressionSet'

Description:

     The expression data are real but anonymized. The data are from an
     experiment that used Affymetrix U95v2 chips. The data were
     processed by dChip and then exported to R for analysis.

     The data illustrate 'ExpressionSet-class', with 'assayData'
     containing the required matrix element 'exprs' and an additional
     matrix 'se.exprs'. 'se.exprs' has the same dimensions as 'exprs'.

     The phenoData and standard error estimates (se.exprs) are made up.
       The information in the "description" slot is fake.

Usage:

     data(sample.ExpressionSet)

Format:

     The data for 26 cases, labeled A to Z and 500 genes. Each case has
     three covariates: sex (male/female); type (case/control); and
     score (testing score).

Examples:

     data(sample.ExpressionSet)
