dimnames

Retrieve the Dimension Names of an RGList, MAList, EList, EListRaw or MArrayLM Object

Description

Retrieve the dimension names of a microarray data object.

Usage

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

Arguments

`x`	an object of class `RGList`, `MAList`, `EList`, `EListRaw` or (not for assignment) `MArrayLM`
`value`	a possible value for `dimnames(x)`: see `dimnames`

Details

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

A consequence is that rownames and colnames will work as expected.

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.
