## Convert Gene Alias to Official Gene Symbols

### Description

Map a set of gene alias names to a set of gene symbols.

### Usage

    alias2Symbol(alias, species = "Hs", expand.symbols = FALSE)

### Arguments

`alias` | character vector of gene aliases
`species` | character string specifying the species. Possible values are `"Dm"`, `"Hs"`, `"Mm"` or `"Rn"`.
`expand.symbols` | logical, should those elements of `alias` which are already official symbols be expanded if they are aliases for other symbols.

### Details

Aliases are mapped via NCBI Entrez Gene identity numbers using Bioconductor organism packages. Species are `"Dm"` for fly, `"Hs"` for human, `"Mm"` for mouse and `"Rn"` for rat. The user needs to have the appropriate Bioconductor organism package installed.

### Value

A character vector of gene symbols. May be longer or shorter than the original vector.
