dimnames {limma}R Documentation

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

Description

Retrieve the dimension names of a microarray data object.

Usage

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

Arguments

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

Details

The dimensionnames of an 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.
