cxxfunction 中的多个插件 [英] Multiple plugins in cxxfunction

问题描述

我想同时使用 RcppGSL 和 RcppArmadillo，是否可以在 cxxfunction(内联 CRAN 包)中使用多个插件?我找到了一种方法:

I want to use RcppGSL and RcppArmadillo at the same time, is that possible to use multiple plugins in cxxfunction (of the inline CRAN package) ? I found a way to do:

plug.ArmaGSL <- Rcpp:::Rcpp.plugin.maker(include.before='#include <RcppArmadillo.h>
                                                     #include <RcppGSL.h>
                                                     #include <gsl/gsl_rng.h>',
                                     Depends=c("RcppGSL", "RcppArmadillo", "Rcpp"),
                                     LinkingTo=c("RcppGSL", "RcppArmadillo", "Rcpp"),
                                     libs="-lgsl -larmadillo")

registerPlugin("RcppArmaGSL", plug.ArmaGSL)

foo <- cxxfunction(signature(sM="numeric"), body=bodytxt, inc=inctxt, plugin="RcppArmaGSL")

但似乎不是那么直观.

推荐答案

好问题.(而且在 rcpp-devel 上会更好.)

Nice question. (And would have been even better on rcpp-devel.)

我认为您需要编写自己的组合插件，详情请参阅 Rcpp-FAQ 小插图的问题 3.6如何为内联包编写插件".

I think you need to write your own combined plugin, see Question 3.6 'How do I write a plugin for the inline package' of the Rcpp-FAQ vignette for details.
