deepblue_extend {DeepBlueR} | R Documentation

## extend

### Description

Extend the genomic regions included in the query. It is possible to extend downstream, upstream or in both directions.

### Usage

    deepblue_extend(query_id = NULL, length = NULL, direction = NULL,
      use_strand = NULL, user_key = deepblue_options("user_key"))

### Arguments

`query_id` | - A string (Query ID)
`length` | - A int (The new region length)
`direction` | - A string (The direction that the region will be extended: 'BACKWARD', 'FORWARD', 'BOTH'. (Empty value will be used for both direction.)
`use_strand` | - A boolean (Use the region column STRAND to define the region direction)
`user_key` | - A string (users token key)

### Value

id - A string (id of the new query)
