hgu95Achrom {annotate} | R Documentation

## 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(eset)
     mget(geneNames(eset)[330:340], env=hgu95Achrom, ifnotfound=NA)
