predict.bs(basis, newx) predict.ns(basis, newx)
basis
|
the result of a call to bs() or ns(), in
particular, having attributes describing knots, degree
etc.
|
newx
|
the x values at which evaluations are required.
|
basis, except evaluated at the new values
of x.
These are methods for the function predict() for objects
inheriting from classes bs or ns. See predict
for the general behavior of this function.
