predict.nsx: Evaluate a Spline Basis

Description

Evaluate a predefined spline basis at given values.

Usage

## S3 method for class 'nsx':
predict(object, newx, \dots)

Arguments

object

the result of a call to nsx 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.

Value

• 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 "nsx". See predict for the general behavior of this function.

Examples

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