我遇到了一个使用 R/quantmod 包的问题。我可以获取韩国的股票信息，但我无法获取日本的信息：

getSymbols("DEXKOUS",src="FRED") #load Korea
[1] "DEXKOUS"
getSymbols("DEXJPUS",src="FRED") #load Japan   
Error as.POSIXlt.character(x, tz, ...) : 
  character string is not in a standard unambiguous format

欢迎您的意见。

你在你的问题中给出的例子对我来说也很好。我得到了 1971 年以后日元兑美元汇率的时间序列。

但是，如果您正在寻找股价数据而不是外汇（您确实说过股票信息？）那么也许您应该尝试 RFinanceYJ 软件包，它从 Yahoo! 中提取股价数据。日本。

require(RFinanceYJ)
sony <- quoteStockXtsData('6758.t', '2011-01-01')
tail(sony,30)
