Hallo, I'm facing a problem and I would really appreciate your support. I have to translate some Matalb code in R that I don't know very well but I would like to. I have to interpolate 5 point with a cubic spline function and then I expect my function returns the Y value as output a specific X value inside the evaluation range. Let's suppose that: 1- *X = [-10, -5, 0, 5, 10]* 2 - *Y = [12, 10, 8, 7, 6]* 3 - *I have to interpolate with a cubic spline assuming x=11*
In Matlab I used this function: *y = interp1(X, Y, x, "cubic"); * How can I do the same in R? Many thanks in advance for your reply and support!
