在小插图中使用未作为示例一部分导入的包

Question

我在我正在开发的包的小插图中使用 forcats 和 devtools 包中的函数。我将它们列在 NAMESPACE 文件的 Suggests（不是 Imports）字段中。

当我运行devtools::check()时，返回如下NOTE：

checking for unstated dependencies in vignettes ... NOTE
'::' or ':::' imports not declared from:
  ‘devtools’ ‘forcats’

根据this question on Stack Overflow, adding these to the Suggests field ought to resolve the issue causing the note, but this doesn't seem to do so for me in this case. Can you recommend how you would address this note? If it is helpful, a link to the package is here的回答。

Answer 1

Suggests 需要添加到您的 DESCRIPTION 文件，而不是 NAMESPACE
