R软件包构建错误 [英] R package building error

问题描述

我正在尝试构建R包。我通常在Rstudio中运行clean and rebuild命令。我现在收到此错误消息：

I am trying to build an R package. I usually run the clean and rebuild command in Rstudio. I am now getting this error message:

==> devtools::document(roclets=c('rd', 'collate', 'namespace', 'vignette'))

Updating ED2io documentation

==> R CMD INSTALL --preclean --no-multiarch --with-keep.source EDio

Exited with status 1.

DESCRIPTION 文件实际上在项目文件夹中，看起来还可以。由于项目中文件太多，因此很难提供可复制的示例。也许有人已经看到此错误。

The DESCRIPTION file is actually in the project folder and seems ok. It's a bit hard to provide a reproducible example because there are so many files in the project. Maybe someone has already seen this error.

推荐答案

原来是 roxygen中缺少的转义字符评论。

＃'@name％==％而不是
＃'@name \％== \％
