More effective search with respect to browsing or digging manually into the documentation. Almost surely I'll find what I need! Thanks very much mggl
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...
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...
Yes, it could be a reasonable choice but I am not sure in general. If min(abs(diff(z))) is significant (global minimum or accentuated local minimum) my abscissa is not uniform a priori without performing the control. 2015-04...
The first solution with diff works for uniform abscissa only with integer values. z <- seq(0, 10, length=100) all(diff(z) == z[2] - z[1] ) ## FALSE In this case, as you recommended, I could use signif or round or...
The aim is to control if a given abscissa/grid is uniform or not. Abscissa in generic vector of real ordered numbers. Here a reproducibile code: # uniform abscissa/grid abscissa1 <- seq(0, 1, length=100) # non-uniform abscissa/grid abscissa2...
