This method function extracts the coefficients associated with the correlation structure represented by object.

Usage

## S3 method for class 'corStruct':
coef(object, unconstrained)
coef(object) <- value

Value

a vector with the coefficients corresponding to object.

SIDE EFFECTS

On the left side of an assignment, sets the values of the coefficients of object to value. Object must be initialized (using initialize) before new values can be assigned to its coefficients.
