Value

An updated object of the same class as the input object with the specified updates.

Arguments

object

Objects of class bSpline2, ibs, mSpline, iSpline, cSpline, bernsteinPoly or naturalSpline with attributes describing knots, degree, etc.

Examples

library(splines2)

x <- seq.int(0, 1, 0.01)
knots <- c(0.3, 0.5, 0.6)

## quadratic B-splines
bsMat2 <- bSpline(x, knots = knots, degree = 2, intercept = TRUE)

## cubic B-splines
bsMat3 <- update(bsMat2, degree = 3)
