gene.mapping {Pigengene} | R Documentation

## Maps gene IDs

### Description

Takse as input gene IDs in a convention, say REFSEQ, and converts them to another convention.

### Usage

    gene.mapping(ids, inputType = "REFSEQ", outputType = "SYMBOL",
      leaveNA = TRUE, inputDb = "Human", outputDb = inputDb,
      verbose = 0)

### Arguments

`ids` | A character vector of input gene IDs
`inputType` | The type of input IDs.
`outputType` | The type of output IDs.
`leaveNA` | If `TRUE`,the IDs that were not matched are left with `NA`s in the second column of the output, otherwise the input IDs are returned.
`inputDb` | The input data base. Use `org.Hs.eg.db` for human and `org.Mm.eg.db` for mouse. The default "Human" character uses the former.
`outputDb` | The output data base.
`verbose` | The integer level of verbosity. 0 means silent and higher values produce more details of computation.

### Details

It can map homologous genes between species e.g. from mouse to human. If more than 1 ID found for an input gene, only one of them is returned.

### Value

A matrix of characters with 3 columns: input, output1, and output2. The last one is guaranteed not to be `NA`.
