R：设置环境名称作为参数new.env（）

Question

有没有办法在调用new.env（）时初始化三个名称“indian”，“pizza”和“ramen”作为参数？

eats <- new.env(
    indian = "8elements", 
    pizza = "blue line", 
    ramen = "orenchi") 

这将是一个替代方案：

eats <- new.env() 
eats$indian = "8elements" 
eats$pizza = "blue line" 
eats$ramen = "orenchi" 

Answer 1

这里有一些选择：

1）创建一个列表，并将其转换为环境

eats <- list2env(list(
    indian = "8elements", 
    pizza = "blue line", 
    ramen = "orenchi")) 

2）另一个po ssibility是使用local这样的：

eats <- local({ 
    indian = "8elements" 
    pizza = "blue line" 
    ramen = "orenchi" 
    environment() 
}) 

3）原癌包创建其实际上环境所以原对象：

library(proto) 
eats <- proto(
    indian = "8elements", 
    pizza = "blue line", 
    ramen = "orenchi")
