如何在R中获取函数的程序包名称? [英] How to get the package name of a function in R?

问题描述

我正在调试一些代码，我认为在2个程序包中可能具有相同功能的两倍.

I'm debugging some code and I think I might have twice the same function in 2 packages.

我想输出该功能的程序包名称，因为它会由R控制台执行.

I want to output the package name of the function as it would be executed by the R console.

示例:

• function_package_name(print)#->基本
• function_package_name(select)#-> dplyr

• function_package_name(print) # --> base
• function_package_name(select) # --> dplyr

我不能简单地使用?select，因为我认为它链接到两个软件包的选择:dplyr和MASS.

I cannot simply use ?select because I think it links to the choice of 2 packages: dplyr and MASS.

我怎么知道我正在使用哪个select功能?

How can I know which select function I'm using ?

注意:这不是列出CRAN上所有功能的重复，也不是的名称，从R中的函数名称中找到包名称，所以sos::findFn()是不可接受的答案！我不是在寻找其他可能像这样的函数，而是在寻找我当前正在使用的函数的包名！

NB : this is NOT a duplicate of list all functions on CRAN, nor of Find the package names from a function name in R, so sos::findFn() is not an acceptable answer ! I'm not looking for potential other functions named like this one, I'm looking for the package name of the one I'm currently using !

推荐答案

也许甚至最方便，如果您紧随软件包名称之后:

Perhaps even most convenient, if you are just after the package name:

environmentName(environment(select))

优点是，它生成一个字符串而不是一个环境对象.

The advantage is that this produces a string rather than an environment object.
