使用devtools :: check时，base :: assign（“。ptime”，proc.time（），pos =“ CheckExEnv”）错误 [英] base::assign(".ptime", proc.time(), pos = "CheckExEnv") ERROR when using devtools::check

问题描述

我正在使用 devtools :: check 对我的软件包进行R CMD检查，并且遇到相同的 ERROR （请参见下方）在此处中进行了讨论。
我尝试执行建议的操作：在＃'@ example ＃'@ export 标签c $ c>在我的 prep.R 代码中，并且我还在<$ c $中添加了 export（prep） c>名称空间。但是我仍然遇到相同的错误。

I am doing the R CMD check for my package using devtools::check and I encountered the same ERROR(see bellow) discussed here. I tried to do what was suggested there: I added a tag of #'@export before the #'@example in my prep.R code, and I also added export(prep) in NAMESPACE. However I still get the same error.

有人知道我该怎么解决吗？

Does anyone knows how can I solve this?

任何帮助都会非常感谢

推荐答案

我在搜寻此确切错误时发现了这个问题，我想我现在明白为什么会这样：Roxygen实际上在 @examples 部分，我的代码包含未声明的对象，并在运行检查时给出了此确切错误。

I found this question when googling this exact error. I think I understand now why it occurred: Roxygen actually executes the code in the @examples section, and my code included undeclared objects and gave this exact error when running check.

快速解决方案：删除 @examples 部分中令人反感的代码行。或者，更体贴的解决方案是将示例代码包含在 \dontrun {... } 。

Quick solution: remove the offending lines of code from the @examples section. Or, a more considerate solution is to enclose the example code within \dontrun{...}.

有关此内容以及其他选项的详细信息，请参见？examples

See ?examples for more details on this as well as other options.
