AlignedDataFrame-class {ShortRead} | R Documentation

## (Legacy) "AlignedDataFrame" representing alignment annotations as a data frame

### Description

This class extends `AnnotatedDataFrame`. It is a data frame and associated metadata (describing the columns of the data frame). The main purpose of this class is to contain alignment data in addition to the central information of `AlignedRead`.

### Objects from the Class

Objects from the class are created by calls to the `AlignedDataFrame` function.

### Slots

`data`:

  Object of class `"data.frame"` containing the data. See `AnnotatedDataFrame` for details.

`varMetadata`:

  Object of class `"data.frame"` describing columns of `data`. See `AnnotatedDataFrame` for details.

`dimLabels`:

  Object of class `character` describing the dimensions of the AnnotatedDataFrame. Used internally; see `AnnotatedDataFrame` for details.

`.__classVersion__`:

  Object of class `"Versions"` describing the version of this object. Used internally; see `AnnotatedDataFrame` for details.

### Extends

Class `"AnnotatedDataFrame"`, directly. Class `"Versioned"`, by class "AnnotatedDataFrame", distance 2.

### Methods

This class inherits methods `pData` (to retrieve the underlying data frame) and `varMetadata` (to retrieve the metadata) from `AnnotatedDataFrame`.

Additional methods include:

append

  `signature(x = "AlignedDataFrame", values = "AlignedDataFrame")`: append `values` after `x`. `varMetadata` of `x` and `y` must be identical; `pData` and `varMetadata` are appended using `rbind`.
