R: Names of a pdMat Object

Names of a pdMat Object

Usage

Names(object)
Names(object) <- value

Arguments

`object`	an object inheriting from class `pdMat`, representing a positive-definite matrix.
`value`	a character vector with the replacement values for the column and row names of the matrix represented by `object`. It must have length equal to the dimension of the matrix represented by `object` and, if names have been previously assigned to `object`, it must correspond to a permutation of the original names.

Description

This method function returns the fist element of the Dimnames attribute of object, which contains the column names of the matrix represented by object.

Value

if object has a Dimnames attribute then the first element of this attribute is returned; otherwise NULL.

SIDE EFFECTS

On the left side of an assignment, sets the Dimnames attribute of object to list(value, value).
