Generate the B-spline basis matrix for a polynomial spline.
Arguments
- x
a numeric vector at which to evaluate the spline. Missing values are not allowed in x
- degree
the degree of the piecewise polynomial
Value
an BSpline list instance
Examples
x_vals <- seq(0, 1, length.out = 6)
bs_obj <- BSpline(x_vals, degree = 3)
dim(bs_obj$y)
#> [1] 6 3
bs_obj$name
#> [1] "bs_x_vals"
