R: Retrieve the Dimension Names of an RGList, MAList, EList,...
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 .
