使用未作为插图中示例的一部分导入的包

我正在使用来自的函数forcats and devtools我正在开发的包的小插图中的包。我已将它们列在Suggests（不是这样的Imports) NAMESPACE 文件中的字段。

当我跑步时devtools::check()，返回以下NOTE：

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

根据答案这个问题在 Stack Overflow 上，将这些添加到“建议”字段应该可以解决导致该注释的问题，但在本例中这对我来说似乎不起作用。您能建议如何处理此说明吗？如果有帮助，包的链接是here.

The Suggests需要添加到您的描述文件，不是命名空间
