将列表的元素作为全局环境中的独立对象返回 [英] Return elements of list as independent objects in global environment

问题描述

我有一个列表，并且想将列表中的元素分解为全局环境中的单独对象.

I have a list, and would like to break the elements of the list into seperate objects in the global environment.

例如，我想要列表:

obj <- list(a=1:5, b=2:10, c=-5:5)

是三个独立的对象a，b和c.

to be three seperate objects a, b, and c.

我试图通过以下方法实现这一目标:

I tried to achieve this with:

lapply(obj, FUN = function(x) names(x)[1] <<- x[1])

但是失败了，使用Error in names(x)[1] <<- x[1] : object 'x' not found.

我如何实现我的目标?

How might I achieve my aim?

推荐答案

有用于将列表映射到环境的特殊功能:

There is special function for mapping list to environment:

> obj <- list(a=1:5, b=2:10, c=-5:5)
> ls()
[1] "obj"
> list2env(obj,globalenv())
<environment: R_GlobalEnv>
> ls()
[1] "a"   "b"   "c"   "obj"
