CNEDensity-methods {CNEr} | R Documentation

## CNEDensity function

### Description

This function queries the database and generates the CNEs' density values.

### Usage

    CNEDensity(dbName, tableName, chr, start, end,
               whichAssembly=c("first", "second"),
               windowSize=300, minLength=NULL)

### Arguments

`dbName` | `character`(1): the path of the local SQLite database.
`tableName` | `character`(1): the name of table for this CNE data table. It can be missing when assembly1, assembly2 and threshold are provided.
`chr` | `character`(1): the chromosome to query.
`start, end` | `integer`(1): the start and end coordinate to fetch the CNEs.
`whichAssembly` | `character`(1): the genome to fetch is in the ‘first’ column or ‘second’ column of the table.
`windowSize` | `integer`(1): the window size in kb that is used to smooth the CNEs.
`minLength` | `integer`(1): the minimal length of CNEs to fetch.

### Value

A `GRanges` object with density values is returned.

### Methods

`signature(tableName = "character", assembly1 = "character", assembly2 = "missing", threshold = "missing")`
`signature(tableName = "missing", assembly1 = "character", assembly2 = "character", threshold = "character")`
