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

"dimnames"(x)
"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

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.

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.
