createBins {QDNAseq} | R Documentation

## Builds bin annotation data for a particular bin size

### Description

Builds bin annotation data for a particular bin size.

### Usage

    createBins(bsgenome, binSize, ignoreMitochondria=TRUE, excludeSeqnames=NULL)

### Arguments

`bsgenome` | A BSgenome package.
`binSize` | A `numeric` scalar specifying the width of the bins in units of kbp (1000 base pairs), e.g. `binSize=15` corresponds to 15 kbp bins.
`ignoreMitochondria` | Whether to ignore the mitochondria, defined as chromosomes named 'chrM', 'chrMT', 'M', or 'MT'.
`excludeSeqnames` | Character vector of seqnames which should be ignored.

### Value

Returns a `data.frame` with columns `chromosome, start, end, bases, and gc`, which correspond to the chromosome name, positions of the first and last base pair in the bin, the percentage of characterized nucleotides (A, C, G, or T, i.e. non-N), and GC content (percentage of C and G nucleotides of non-N nucleotides).
