Question

我从R的yahoo财务网站下载一些股票数据时出现错误。我正在使用tseries包中的get.hist.quote函数。

上周，没有问题。

可能代码如下：

library(tseries)

data<-get.hist.quote(instrument = "EREGL.IS,
                     provider="yahoo",
                     quote=c("Open","High","Low","Close","AdjClose","Volume"),
                     start="2010-01-01",
                     end="2017-02-03",
                     compression="d",
                     retclass="zoo")

`

我收到以下错误：

为什么会出现此错误？一种可能性是更改相关网址的名称。

如何解决此问题？我会很高兴得到任何帮助。非常感谢。

雅虎做了一些更改，因此如果没有相应的“碎屑”，您将无法访问下载，请参阅Question few days ago。
除非您想手动复制粘贴每个股票的下载URL，否则我强烈建议您使用quantmod包。它应用了一个简短的修复程序（可能很快就会包含在新的软件包版本中 - 直到那时你必须手动完成）。

library(quantmod)   #probably will need to install the package first
devtools::install_github("joshuaulrich/quantmod", ref="157_yahoo_502")    #installing the fix (devtools necessary)

str(getSymbols("EREGL.IS",auto.assign=F,from="2010-01-01",to="2017-02-03"))    #Example
#An ‘xts’ object on 2010-01-01/2017-02-03 containing:
#  Data: num [1:1851, 1:6] 4.39 4.43 4.42 4.49 4.49 ...
# - attr(*, "dimnames")=List of 2
#  ..$ : NULL
#  ..$ : chr [1:6] "EREGL.IS.Open" "EREGL.IS.High" "EREGL.IS.Low"     #"EREGL.IS.Close" ...
#  Indexed by objects of class: [Date] TZ: UTC
#  xts Attributes:  
#List of 2
# $ src    : chr "yahoo"
# $ updated: POSIXct[1:1], format: "2017-05-20 12:11:08"

使用R
