predict.bs {splines} | R Documentation |
Evaluate a predefined spline basis at given values.
predict.bs(object, newx, ...) predict.ns(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. Presently no additional arguments are used. |
An object just like basis
, 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.
