## Convert other common IDs to entrez gene ID.

### Description

Convert other common IDs such as ensemble gene id, gene symbol, refseq id to entrez gene ID leveraging organism annotation dataset. For example, org.Hs.eg.db is the dataset from orgs.Hs.eg.db package for human, while org.Mm.eg.db is the dataset from the org.Mm.eg.db package for mouse.

### Usage

    convert2EntrezID(IDs, orgAnn, ID_type="ensembl_gene_id")

### Arguments

`IDs` | a vector of IDs such as ensembl gene ids
`orgAnn` | organism annotation dataset such as org.Hs.eg.db
`ID_type` | type of ID: can be ensemble_gene_id, gene_symbol or refseq_id

### Value

vector of entrez ids
