我正在使用TWS API，但它不适合我。我让它接近我想做的事情，但我一直在努力找出如何正确使用lappy函数

以下是我目前要做的工作：

library("IBrokers")
tws <- twsConnect()
tickers <- c("AAPL","YHOO")
reqMktData(tws, lapply(tickers, twsSTK), tickGenerics="", snapshot=T)
twsDisconnect(tws)

library（“IBrokers”）

tws我错误地阅读了Lappy上的文档。有关我的解决方案，请参阅附件


library("IBrokers")
tws <- twsConnect()
tickers <- c("AAPL","YHOO","MSFT","GLD")
reqMktData(tws, lapply(tickers, twsSTK, exch = "ISLAND", currency = "USD"), tickGenerics="", snapshot=T)
twsDisconnect(tws)



library（“IBrokers”）
tws

library("IBrokers")
tws <- twsConnect()
tickers <- c("AAPL","YHOO","MSFT","GLD")
reqMktData(tws, lapply(tickers, twsSTK, exch = "ISLAND", currency = "USD"), tickGenerics="", snapshot=T)
twsDisconnect(tws)
