Example Package using splines2 with Rcpp

Since v0.3.0, the splines2 package provides C++ interface for constructing regression spline basis functions. This repository contains an example package that demonstrates its usage with help of Rcpp.

Get Started

Firstly, in DESCRIPTION, we need

• include Rcpp in Imports
• include Rcpp, RcppArmadillo, and splines2 (>=0.3.0) in LinkingTo

Secondly, we need add the following lines to a C++ script:

#include <RcppArmadillo.h>
// [[Rcpp::plugins(cpp11)]]

// include header file from splines2 package
#include <splines2Armadillo.h>

Then we have access to the routines to create spline basis functions under name space named splines2. For example, we may create a default B-spline object as follows:

splines2::BSpline bs_obj;

See one of the splines2 package vignettes for more detailed introduction to the C++ interface.
