由于搜索路径上的名称冲突，如何在R中取消屏蔽功能 [英] How to unmask a function in R, due to name collisions on searchpath

问题描述

当我加载软件包debug来调试具有zoo对象的脚本时，我遇到了麻烦:zoo中的函数index被debug软件包屏蔽了.我如何取消对index的遮罩?一般来说，如何处理这些名称冲突问题?我们只是不将debug软件包与`zoo'一起使用?

When I loaded package debug to debug a script with zoo objects, I got trouble: function index from zoo got masked by debug package. How can I unmask index? In general, how to deal with these name colliding problems? We just do not use debug package with `zoo'?

推荐答案

导出的符号始终可以通过::运算符识别:

Exported symbols are always identifiable with the :: operator:

zoo::index

未在名称空间中声明的隐藏函数仍可以使用:::(三元冒号)进行访问，示例为

Hidden functions not declared in the namespace can still be accessed using ::: (triple-colon), and example would be

zoo:::.onLoad

即使未导出也可以看到.

which you can see even though it is not exported.
