data:sample.ExpressionSet: 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
