txLength {casper} | R Documentation

## ~~ Methods for Function `txLength` in Package casper ~~

### Description

~~ Methods for function `txLength` in package casper ~~ Function to retrieve transcript lengths from annotated genome (class genomeDB).

### Usage

      txLength(islandid, txid, genomeDB)

### Arguments

`islandid` | Retrieve length for transcripts in island `islandid`.
`txid` | Retrieve length for `txid` transcripts.
`genomeDB` | Annotated genome of class `genomeDB`.

### Details

When called for the first time lengths are calculated and stored in the object `genomeDB`. Subsequent calls refer to these computed values.

### Value

Named numeric vector with transcript lengths.

### Methods

`signature(islandid = "character", txid = "missing", genomeDB = "annotatedGenome")`

  Retrieve lengths from genomeDB for transcripts in `islandid` islands.

`signature(islandid = "missing", txid = "character", genomeDB = "annotatedGenome")`

  Retrieve lengths from `genomeDB` for `txid` transcripts.

`signature(islandid = "missing", txid = "missing", genomeDB = "annotatedGenome")`

  Retrieve or calculate lengths for all transcripts in the annotated genome `genomeDB`.
