Evaluate a Spline Basis


Evaluate a predefined spline basis at given values.


## S3 method for class 'bs':
predict(object, newx, ...)

## S3 method for class 'ns':
predict(object, newx, ...)


object the result of a call to bs or ns having attributes describing knots, degree, etc.
newx the x values at which evaluations are required.
... Optional additional arguments. At present no additional arguments are used.


An object just like object, except evaluated at the new values of x.
These are methods for the generic function predict for objects inheriting from classes "bs" or "ns". See predict for the general behavior of this function.

bs, ns, poly.


basis <- ns(women$height, df = 5)
newX <- seq(58, 72, len = 51)
# evaluate the basis at the new data
predict(basis, newX)
