| coef.corStruct {nlme} | R Documentation |
This method function extracts the coefficients associated with the
correlation structure represented by object.
## S3 method for class 'corStruct': coef(object, unconstrained, ...) ## S3 method for class 'corStruct': coef(object, ...) <- value
object |
an object inheriting from class corStruct,
representing a correlation structure. |
unconstrained |
a logical value. If TRUE the coefficients
are returned in unconstrained form (the same used in the optimization
algorithm). If FALSE the coefficients are returned in
"natural", possibly constrained, form. Defaults to TRUE. |
value |
a vector with the replacement values for the coefficients
associated with object. It must be a vector with the same length
of coef{object} and must be given in unconstrained form. |
... |
some methods for this generic require additional arguments. None are used in this method. |
a vector with the coefficients corresponding to object.
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.
