hgu95Achroloc {annotate} | R Documentation

## Annotation data for the Affymetrix HGU95A GeneChip

### Description

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

### Usage

    data(hgu95Achroloc)

### Format

These data sets provide environments with mappings from the Affymetrix identifiers to chromosomal location, in bases. The environments function like hashtables 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(hgu95Achroloc)
     data(sample.ExpressionSet)
     mget(featureNames(sample.ExpressionSet)[330:340], env=hgu95Achroloc,
           ifnotfound=NA)
