如何使用R獲取所有S＆P500 corp代碼列表？

Question

我想在R中進行FOR語句分析股票數據。

但我不知道如何獲得S & P corp代碼列表。

請讓我知道解決方案。

謝謝。

library(rpart) 
library(rpart.plot) 
library("quantmod") 
startDate = as.Date("2012-01-01") 
endDate = as.Date("2014-01-01") 
getSymbols("005930", src = "google", from = startDate, to = endDate)

如果使用彭博/路透社或任何其它數據提供者，那麼你可以簡單地得到任何你在Excel中想要的，然後讀給R和然後進行下載歷史數據。如果你沒有獲得這樣的商業數據提供者，然後的方式之一是網頁抓取（我相信維基百科是足夠可靠的，但做仔細檢查）：

library(rvest) 
url <- "https://en.wikipedia.org/wiki/List_of_S%26P_500_companies" 
SP500 <- url %>% 
    html() %>% 
    html_nodes(xpath='//*[@id="mw-content-text"]/div/table[1]') %>% 
    html_table() 
SP500 <- SP500[[1]] 
Tix <- SP500$`Ticker symbol` 
Tix 

截至今日，S &的成分P500：
