Plot basis spline functions

Plot basis spline functions

viewBasis(knots, degree)

Arguments

knots

A vector of values between 0 and 1, specifying cut-points for splines

degree

Integer specifying degree of curvature.

Value

A ggplot object that contains a plot of the basis functions. In total, there will be length(knots) + degree + 1 functions plotted.

Examples

knots <- c(0.25, 0.50, 0.75)
viewBasis(knots, degree = 1)


knots <- c(0.25, 0.50, 0.75)
viewBasis(knots, degree = 2)


knots <- c(0.25, 0.50, 0.75)
viewBasis(knots, degree = 3)
