我试图使用此代码使用quantmod获取符号数据。
getSymbols(c("^DJI"),src='yahoo',from='2014-11-24',to='2017-11-24')
我收到错误
Error in 'colnames<-'('*tmp(', value = c("DJI.open", "DJI.High", "DJI.Low", :
length of 'dimnames' [2] not equal to array extent
感谢您的帮助。
编辑：我在普通代码中遇到同样的错误。
getSymbols(c("DWDP","AAPL","MCD","MRK","IBM","MMM","KO","DIS","CSCO","PG","TRV","UTX","HD","PFE","MSFT","VZ","GS","WMT","GE","INTC","BA","JPM","AXP","XOM","NKE","CAT","CVX","JNJ","UNH","V"),src='yahoo',from='2014-11-24',to='2017-11-24')
答案 0 :(得分：0)
没有c。只是做
getSymbols('^DJI', src = 'yahoo', from = '2014-11-24', to = '2017-11-24')
回复编辑：
也许你的包和/或R已经过时了。我运行了你的确切代码
getSymbols(c("DWDP","AAPL","MCD","MRK","IBM","MMM","KO","DIS","CSCO","PG","TRV","UTX","HD","PFE","MSFT","VZ","GS","WMT","GE","INTC","BA","JPM","AXP","XOM","NKE","CAT","CVX","JNJ","UNH","V"),src='yahoo',from='2014-11-24',to='2017-11-24')
并且能够获得所有价格。
