问题描述

我已经使用以下命令很长时间了，没问题:

I have been using the following command for a long time without problem:

spy <- read.csv("http://ichart.finance.yahoo.com/table.csv?s=SPY")

但是在过去的几天里，它开始引发以下错误:

But in the past few days it started to throw the following error:

警告消息:

Warning messages:

1:在file(file，"rt")中: 内部"方法无法处理https重定向到:' https://ichart.finance .yahoo.com/table.csv?s = SPY '

1: In file(file, "rt") : "internal" method cannot handle https redirection to: 'https://ichart.finance.yahoo.com/table.csv?s=SPY'

2:在file(file，"rt")中:"internal"方法失败，因此尝试使用"libcurl"

2: In file(file, "rt") : "internal" method failed, so trying "libcurl"

我已经将RStudio，R和所有软件包更新为今天的最新版本.有人可以帮我解决这个问题吗?

I've updated my RStudio, R and all packages to the most up-to-date versions as of today. Could someone help me resolve this issue?

提前谢谢！

推荐答案

错误消息中的修复程序就在那里:使用 https 而不是http:

The fix is right there in the error message: use https not http:

R> spy <- read.csv("https://ichart.finance.yahoo.com/table.csv?s=SPY")
R> head(spy)
