drop {ChIPanalyser} | R Documentation

## Accessor Method for the `drop` slot in a `genomicProfiles` object.

### Description

Accessor Method for the `drop` slot in a `genomicProfiles` object.

### Usage

    drop(object)

### Arguments

`object` | `object` is a `genomicProfiles` object.

### Details

During certain computations, it is possible that the Loci of interest do no show any overlap with accesible DNA. If this were to be the case, a warning message will appear in the console but these inaccessible Loci will be stored in this slot. It is also for these reasons that it is imperative for Loci of interest to be named (in this case, a named `GRanges`).

### Value

Returns a character string with loci containing no accesible DNA.

### Examples

    # Loading data
    data(ChIPanalyserData)
    #Loading PFM files
    PFM <- file.path(system.file("extdata",package="ChIPanalyser"),"BCDSlx.pfm")
    #Building data objects
    GPP <- genomicProfiles(PFM=PFM,PFMFormat="raw")

    # Loci with no acces - a warning message will be issued
    #if loci do no contain accesible DNA
    # Otherwise this slot will remain empty

    drop(GPP)
