hgu95Achrom: Annotation data for the Affymetrix HGU95A GeneChip

Description

Data, in the form of environments for the Affymetrix U95A chip.

Usage

data(hgu95Achrom)

Format

This data set provides an environment (treat as a hashtable) with mappings from the Affymetrix identifiers to chromosome number/name. The environment functions like a hashtable and can be accessed using mget. If the returned value is NA then the current mapping was unable to identify this. Mappings and data sources are constantly evolving so updating often is recommended.

Source

The AnnBuilder package.

Examples

 data(hgu95Achrom)
 data(sample.ExpressionSet)
 mget(featureNames(sample.ExpressionSet)[330:340], env=hgu95Achrom, ifnotfound=NA)
