我有一个R使用roxygen2. 它有一些C代码/src,我刚刚开始使用Doxygen. 有什么方法可以结合文档或将编译与 roxygen2 集成?C将代码文档放在哪里的任何“最佳实践” ?

谷歌搜索 roxygen2 和 doxygen 主要导致roxygen 类似于 doxygen结果。我发现了一些带有 Doxyfiles 的包,但没有一致的组织。例如,lme4输出到源目录之外的inst/doc/Doxyfile一个文件夹。在 Matrix 的根目录下还有一个 Doxyfile(但在以前的版本中是在.doxygenlme4inst

是否有任何理由不将C文档包含在包中,或者为什么 Doxygen 很少在 R 包中使用,尽管广泛使用C?

我个人在我在所有脚本中调用的“dataManagement”包中使用以下代码。它有 roxygen 文档和示例。实际上,您只需调用 document() 并在 src/ 中的 C 代码上运行 doxygen。该文档放在 inst/doxygen 中,以便您的包准备好 CRAN。

R 文档是为不应该查看 C 代码的 R最终用户设计的.
