我刚下载了包Quantmod,一直在玩getSymbols.我希望能够获得多个股票的数据,就像这个问题:getSymbols并使用lapply,Cl和merge来提取收盘价.

不幸的是,当我试图复制答案时:

tickers <- c("SPY","DIA","IWM","SMH","OIH","XLY",
         "XLP","XLE","XLI","XLB","XLK","XLU")
getSymbols(tickers, from="2001-03-01", to="2011-03-11")

我收到以下错误消息:

Error in download.file(paste(yahoo.URL, "s=", Symbols.name, "&a=", from.m,  :
cannot open URL 
'http://chart.yahoo.com/table.csv?s=SPY&a=2&b=01&c=2001&d=2&e=11&f=2011&g=d&q=q&y=0&z=SPY&x=.csv'
In addition: Warning message:
In download.file(paste(yahoo.URL, "s=", Symbols.name, "&a=", from.m,
: cannot open: HTTP status was '0 (null)'

这是我的sessionInfo()
