If is specify a spline basis as follows knots <- c(6, 12, 22, 30, 35) x <- c(0.0, .25, 1.0, 2.0, 3.0) SCurve <- bs(x = x, knots = knots, intercept = FALSE, Boundary.knots = c(0,3.5))
I would like to now get the spline value for new values of x. However, when I use predict the new basis is returned and I would like to get the value. Nothing has worked so far and ?predict plus examples only show prediction from linear models. Is there a way to extract the value from a defined spline?
