getSYMBOL {EMBO03} | R Documentation

## Functions to deal with Data Packages

### Description

The functions documented here are intended to make it easier to map from a set of manufacturers identifiers (such as you will get from the chips etc) to other identifiers.

### Usage

    getSYMBOL(x, data = "hgu95a")
    getLL(x, data = "hgu95a")
    getGO(x, data = "hgu95a")
    getPMID(x, data = "hgu95a")
    getGOdesc(x, which=c("MF","BP","CC") )

### Arguments

`x` | The identifiers to be mapped (usually manufacturer)
`data` | A character string identifying the data source
`which` | For `getGOdesc` indicates which GO hierarchy to use.

### Details

Appropriate translations are done. In some cases such as `getLL` and `getSYMBOL` there will only be one match and a vector is returned. In other cases such as `getPMID` and `getGO` there may be multiple matches and a list is returned. For `getGOdesc` the input vector is GO identifiers (not manufacturer identifiers) and in the output any identifier that does not have a description in the selected GO hierarchy (MF, BP or CC) is dropped.

### Value

Either a vector or a list depending on whether multiple values per input are possible.

### Examples

      data(eset)
      gN <- geneNames(eset)[100:105]
      getSYMBOL(gN)
      gg<- getGO(gN)
      getGOdesc(gg[[2]], "MF")
      getLL(gN)
      getPMID(gN)
