So data points in the two extreme intervals (i.e., outside the two boundary knots) are wasted since they do not a↵ect the fitting. Therefore, by default, R puts the two boundary knots as the min and max of x i’s. • You can tell R the location of knots, which are the interior knots. Recall

WebSpline functions are formed by joining polynomials together at fixed points called knots. That is, we divide the interval extending from lower limit tL to upper limit tU over which we wish to approximate a curve into L+1 sub-intervals separated by L interior boundaries ξl called knots, or sometimes breakpoints .)
