我想在R中使用FOR语句一次性分析股票数据。
但我不知道如何获得S＆amp; P公司代码清单。
请让我知道解决方案。
谢谢。

如果您使用彭博/路透社或任何其他数据提供商，那么您可以在Excel中获得您想要的任何内容，然后将其读取到R，然后继续下载历史数据。如果您无法访问此类商业数据提供商，那么其中一种方式是网络抓取（我相信维基百科足够可靠，但需要仔细检查）：
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
截至今天，S＆amp; P500的成分：

您可以使用BatchGetSymbols软件包，该软件包还会通过抓取Wikipedia来获取列表。
library(BatchGetSymbols)
sp500 <- GetSP500Stocks()
sp500$tickers
