Quantmod getSymbolsエラー

Question

私はこのコードを使用してquantmodでシンボルデータを取得しようとしています。

getSymbols(c("^DJI"),src='yahoo',from='2014-11-24',to='2017-11-24') 

そして、私はエラーに任意のヘルプ

Error in 'colnames<-'('*tmp(', value = c("DJI.open", "DJI.High", "DJI.Low", : 
    length of 'dimnames' [2] not equal to array extent 

感謝を取得します。

編集：通常のティッカーでも同じエラーが表示されます。

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') 

Answer 1

cなし。

たぶん、あなたのパッケージおよび/またはRが古いです：ちょうど編集する

getSymbols('^DJI', src = 'yahoo', from = '2014-11-24', to = '2017-11-24') 

返信を行います。私はあなたの正確なコード

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')

を実行し、すべての価格を取得することができました。
