is supplemented by the command Rcpp::compileAttributes().
To access newly written or modified C++ and R functions from the
terminal, run:Tailplots uses the R package Rcpp to integrate C++ code with R. One advantage of Rcpp is its extensive documentation, and many guides are available.
Under R/ you’ll find the package’s R code and two
additional files, R/zzz.R and R/RcppExports.R.
The first file sets the imports for the Tailplots package and can
probably be removed now. The second contains the wrapper functions that
connect the C++ code to R and shouldn’t be edited by hand (see the
workflow below).
In the src/ folder you’ll find the C++ code. The only
files that should be edited by hand are gamma.cpp and
pareto.cpp; the other files are generated automatically by
Rcpp. Any C++ function that you want to export and make available after
devtools::load_all() must have the line
// [[Rcpp::export]] immediately above the function
definition. Include the following at the beginning of each C++ file:
#include <Rcpp.h>
using namespace Rcpp;The rest is standard C++ code.
Note that the DESCRIPTION file contains:
Imports:
Rcpp
LinkingTo:
RcppThe usual R package workflow described in R Packages (2e)
is supplemented by the command Rcpp::compileAttributes().
To access newly written or modified C++ and R functions from the
terminal, run:
Rcpp::compileAttributes()
devtools::load_all()Everything else remains the same.
