本文介绍了R中的屏蔽函数列表的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我使用了很多包，我知道有些功能被屏蔽了，因为它们存在于几个不同的包中.有没有办法获取重复函数(或屏蔽函数)的列表?

I use a lot of packages and I know some functions are masked because they exist in several different packages.Is there a way to get the list of duplicate functions (or masked functions?)

理想的情况是有一个重复函数列表，并为每个函数提供它所在的包列表.

The ideal would be to have a list of duplicate function and for each of them, the list of packages in which it exists.

推荐答案

in R base:

 conflicts(detail=TRUE)

并找到包含一个版本的环境列表

And to find the list of environments that contain a version of

getAnywhere(x = "functionA")

注意:getAnywhere 还可以找到未导出的函数.因此不会产生冲突.

Note: getAnywhere also finds the functions which are not exported. and that are hence not creating conflicts.

使用以下方法可以获得更好(更简单)的结果:

A better (simpler) result could be obtained using:

x = "functionA"
names(which(sapply(search(), FUN = function(env) exists(x, env, inherits = FALSE, mode = "function"))))
