使用未作为插图中示例的一部分导入的包

Question

我正在为我正在开发的包使用小插图中的forcats和包中的函数。devtools我将它们列在NAMESPACE 文件的Suggests(not not ) 字段中。Imports

\n\n

当我运行时devtools::check()，会返回以下注释：

\n\n

checking for unstated dependencies in vignettes ... NOTE\n\'::\' or \':::\' imports not declared from:\n  \xe2\x80\x98devtools\xe2\x80\x99 \xe2\x80\x98forcats\xe2\x80\x99\n

\n\n

根据Stack Overflow 上这个问题的答案，将这些添加到“建议”字段应该可以解决导致该注释的问题，但在这种情况下，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，这里有一个包的链接。

建议需要添加到您的描述文件中，而不是命名空间中
