R：設置環境名稱作爲參數new.env（）

Question

有沒有辦法在調用new.env（）時初始化三個名稱「indian」，「pizza」和「ramen」作爲參數？

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

這將是一個替代方案：

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

Answer 1

這裏有一些選擇：

1）創建一個列表，並將其轉換爲環境

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

2）另一個po ssibility是使用local這樣的：

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

3）原癌包創建其實際上環境所以原對象：

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