[R] Smooth line in graph

Hi, I’m trying to get smooth curves connecting points in a plot using spline but I don’t get what I whant. Eg.: x-1:5 y - c(0.31, 0.45, 0.84, 0.43, 0.25) plot(x,y) lines(spline(x,y)) Creates a valley between the first and second points, then peaks at 3rd, and another valley between 4th and

Re: [R] Smooth line in graph

how about: require(splines) x-1:5 y - c(0.31, 0.45, 0.84, 0.43, 0.25) yy -predict(interpSpline(x, y)) plot(x, y) lines(yy) Katharine Mullen mail: Department of Physics and Astronomy, Faculty of Sciences Vrije Universiteit Amsterdam, de Boelelaan 1081 1081 HV Amsterdam, The Netherlands
