[R] NATURAL Smoothing B-splines

Hi all, I'm an engineering student from Politecnico di Milano. I want to perform Smoothing using Smoothing B-splines on syntethic data. The splines must be NATURAL (at the edges the second and third order derivates are zero). How can I impose this constraint? I have searched in R documentation. Fo

[R] Verify that a grid is uniform

I need to control of a given grid is uniform. This control using signif until now works: if (all(signif(abscissa[1:(length(abscissa) - 1) + 1] - abscissa[1:(length(abscissa) - 1)]) == signif(rep((range(abscissa)[2] - range(abscissa)[1])/(length(abscissa) - 1), length(abscissa) - 1 { #
