描述元信息中的错误

Question

我是 R 包开发的新手，我不确定这是否是常见错误。我正在开发一个可以在 GitHub 上找到的新包：https://github.com/jroberayalas/ahnr。我在装有 OS X Yosemite [平台：x86_64-apple-darwin13.4.0 (64-bit)] 的 Mac 上使用 R 版本 3.3.0 (2016-05-03)。

当我检查包时，我收到 1 个描述元信息的错误。它没有提供任何有意义的细节，我不确定这是什么意思。

下面是我按下 CMD+Shift+E 时得到的输出。我觉得奇怪的是，我认为包裹被检查了两次：第一次是checking DESCRIPTION meta-information ... OK，第二次是checking DESCRIPTION meta-information ... ERROR。我不知道这是否是它应该工作的方式。我必须补充一点，GitHub 存储库存储在我的 Google Drive 文件夹中以便存储在云端，所以我不确定这是否会导致错误。

Answer 1

感谢@DKangeyan，问题似乎与 R 中的 LOCALE 功能有关。我按照说明进行操作 here 和 here，问题就解决了。

根据编写R扩展手册https://cran.r-project.org/doc/manuals/r-release/R-exts.html#The-DESCRIPTION-file，你应该避免提及你的包的名字，甚至是包这个词。您可以尝试在描述的开头不使用This package。它应该可以为您解决问题，因为我没有看到任何其他问题。
