I assigned your str to the variable z. And then did this z.s <- spline(z[,1],z[,2]) z.range <- 1:50 plot(z.s$x[z.range],z.s$y[z.range]) lines(z.s$x[z.range],z.s$y[z.range], col=2) z.range <- 401:450 plot(z.s$x[z.range],z.s$y[z.range]) lines(z.s$x[z.range],z.s$y[z.range], col=2) And got the distinct impression that the spline is going through your points. So what have you done and what made you draw your conclusion?
