нагрузка новозеландская цена акций от Yahoo финансов

Question

Noobie здесь ребята поэтому, пожалуйста, быть нежным :)

Я пытаюсь загрузить данные из Yahoo Finance, используя quantmod для всех новозеландских перечисленных запасов. Следующее - это то, что у меня есть. Но, по-видимому, данные отсутствуют, когда я пытаюсь заглянуть внутрь. Что я делаю не так?

library(TTR) 
library(quantmod) 
install.packages("PerformanceAnalytics") 
library(PerformanceAnalytics) 

#Make a new environment for quantmod to store data in 
stockData <- new.env() 

#Specify period of time we are interested in 
startDate = as.Date("2009-01-01") 
endDate = as.Date("2014-01-30") 

#Define the tickers we are interested in

#Download the stock history (for all tickers) 
sdata <- getSymbols(tickers, env = stockData, src = "yahoo", from = startDate, to = endDate) 
stockinf <- stockData$sdata 
head(stockinf) 

Answer 1

Полученные символы находятся в округе stockData. По умолчанию getSymbols вернет имя тикера и сохранит объект в указанной среде.

sdata 
## [1] "ABA.NZ" 


ls(stockData) 
## [1] "ABA.NZ" 


head(stockData$ABA.NZ)
