## Ribosome Release Score (RRS)

### Description

RRS is calculated as the ratio of translational efficiency in the CDS with RPFs in the 3'UTR.

### Usage

    ribosomeReleaseScore(
      cdsTE,
      utr3TE,
      CDSsampleOrder,
      UTR3sampleOrder,
      pseudocount = 0,
      log2 = FALSE
    )

### Arguments

`cdsTE, utr3TE` | Translational efficiency of CDS and UTR3 region. Output of translationalEfficiency
`CDSsampleOrder, UTR3sampleOrder` | Sample order of cdsTE and utr3TE. The parameters are used to make sure that the order of CDS and UTR3 in TE is corresponding samples.
`pseudocount` | The number will be add to sum of reads count to avoid X/0.
`log2` | Do log2 transform or not.

### Value

A vector of RRS.
