R中的掩码函数列表 [英] list of masked functions in R

问题描述

我使用了很多软件包，我知道一些功能被屏蔽，因为它们存在于几个不同的软件包中。
有没有办法获取重复的功能（或掩码函数）的列表？

理想的方法是将一个重复的功能列表和每个在其中存在的包的列表。

解决方案

在R base：

  conflict（detail = TRUE）
  

并找到包含

  getAnywhere（x =functionA）
  

注意： getAnywhere 还查找不导出。因此不会产生冲突。

可以使用以下方式获得更好（更简单）的结果：

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

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?)

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

解决方案

in R base:

 conflicts(detail=TRUE)

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

getAnywhere(x = "functionA")

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

A better (simpler) result could be obtained using:

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