Thanks for this bug report. I've replicated the problem using
your excellent example. Unfortunately, this may not be an easy bug to
fix.
Might it be feasible for you to use either the 'periodicSpline'
function in the 'splines' package or a Fourier basis in the 'fda' package?
Hello:
The following shows how to fit a simple periodic function to data
using Fourier bases in the 'fda' package. Fixing the bug you reported
in the 'percur' function may not be easy. (To my knowledge, the primary
capability in the 'DierckxSpline' package not otherwise available in R
I've just encountered a segfault when using DierckxSpline::percur
function. Below is the minimal example which triggers the error:
---
library(DierckxSpline)
x - 1:10
y - rep(0, 10)
pspline - percur(x, y)
