getHomoGeneIDs {GeneAnswers} | R Documentation

## Get homologous genes of given genes

### Description

Map given gene IDs to homologous gene IDs.

### Usage

    getHomoGeneIDs(oriGeneIDs, species = c("human", "rat", "mouse", "yeast", "fly"), speciesL = c("human", "rat", "mouse", "yeast", "fly"), mappingMethod = c("direct", "biomaRt", "none"))

### Arguments

`oriGeneIDs` | a given entrez gene IDs
`species` | species of the current genes
`speciesL` | species of the mapped genes
`mappingMethod` | mapping method, see details

### Details

There are two mapping methods supported by current version. "direct" only works between human and mouse because most of human gene symbols are capitalized and only the first letter is uppercase for those homogenes in mouse. Another way is by means of package "biomaRt" ,which contains more information while the network connection is necessary to access biomaRt online server.

### Value

return homologous gene IDs of given genes
