如何在R中获取变量的环境 [英] How to get environment of a variable in R

问题描述

我想知道是否有任何方法可以获得声明变量的环境.假设我已经向环境声明了一个变量，并且想使用该变量的环境来声明更多变量.类似 getEnv("variable")

I was wondering if there is anyway to get the environment of a declared variable. Say I already have declared a variable to an environment and want to use that variable's environment to declare a few more variables. Something like getEnv("variable")

推荐答案

参考:http://adv-r.had.co.nz/Environments.html#env-basics

library(pryr)
x <- 5
where("x")
#> <environment: R_GlobalEnv>
where("mean")
#> <environment: base>

where 函数在上面的网站中有描述.它只找到变量出现的第一个环境，但可以轻松修改以找到所有环境.

The where function is described in the above website. It only finds the first environment the variable appears in, but could easily be modified to find all.
