GroupComp.data: Sample ExpressionSet of GroupComp.data

Description

An ExpressionSet object of GroupComp.data

Usage

data(GroupComp.data)

Value

expr(GroupComp.data)

A matrix with 100 rows and 83 columns with rows representing probe-sets and cloumns of human sample IDs.

pData(GroupComp.data)

A data frame with 83 rows and 2 columns. Each row represents one human sample. Column id is the human sample ID and sppfst.grps is the assigned sample group label.

Details

GroupComp.data is an ExpressionSet object with the expression data from Johnson et al (2010) for 100 randomly selected genes. The expression data was collected from 83 subjects with ependymoma defined by anatomic subclass (grp1 = posterior fossa, grp2 = supratentorial, grp3 = spinal). The data set is used for an example of using the package for a comparison of expression across 3 groups.
