dimnames

Retrieve the Dimension Names of a DGE Object

Description

Retrieve the dimension names of a digital gene expression data object.

Usage

## S3 method for class 'DGEList'
dimnames(x)
## S3 replacement method for class 'DGEList'
dimnames(x) <- value

Arguments

`x`	an object of class `DGEList`, `DGEExact`, `DGEGLM`, `DGELRT` or `TopTags`
`value`	a possible value for `dimnames(x)`, see `dimnames`

Details

The dimension names of a DGE data object are the same as those of the most important component of that object.

Setting dimension names is currently only permitted for DGEList or DGEGLM objects.

A consequence of these methods is that rownames, colnames, rownames<- and colnames<- will also work as expected on any of the above object classes.

Value

Either NULL or a list of length 2. If a list, its components are either NULL or a character vector the length of the appropriate dimension of x.
