| predict.bs {splines} | R Documentation |
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.
basis <- ns(women$height, df = 5) newX <- seq(58, 72, len = 51) # evaluate the basis at the new data predict(basis, newX)
