predict.bs

From splines v3.5.1 by R-core R-core@R-project.org

Evaluate a Spline Basis

Evaluate a predefined spline basis at given values.

Keywords: smooth

Usage

# S3 method for bs
predict(object, newx, …)
# S3 method for ns
predict(object, newx, …)

Arguments

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.

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 "bs" or "ns". See predict for the general behavior of this function.

Examples

library(splines)

# NOT RUN {
require(stats)
basis <- ns(women$height, df = 5)
newX <- seq(58, 72, length.out = 51)
# evaluate the basis at the new data
predict(basis, newX)
# }
