在同一包装上使用roxygen2和doxygen？[关闭]

我有一个R使用的软件包roxygen2。它在中有一些C代码/src，而我刚开始使用Doxygen。有什么方法可以合并文档或将编译器与roxygen2集成在一起？在哪里放置C代码文档有“最佳实践” 吗？

对roxygen2和doxygen进行谷歌搜索主要导致roxygen与doxygen结果相似。我发现了一些带有Doxyfiles的软件包，但是没有一致的组织。例如，lme4已inst/doc/Doxyfile输出到源目录doxygen外部的文件夹lme4。Matrix的根目录中也有一个Doxyfile（但在以前的版本中是inst。该文档也被导出到package目录之外。

是否有任何理由不将C文档包含在软件包中，或者尽管Doxygen广泛使用，为什么Doxygen在R软件包中却很少使用C？

更新：请参阅相关的roxygen2功能请求

我亲自在所有脚本中调用的“ dataManagement”包中使用以下代码。它具有roxygen文档和示例。您实际上只是调用document（）并在src /中的C代码上运行了doxygen。将文档放在inst / doxygen中，以便您的软件包可用于CRAN。

专为R 最终用户设计的R文档不应查看C代码我没有将C代码文档集成到经典R文档中，但是将生成的C文档复制为“渐晕”可能是一个好习惯。
