这是我的代码：
library(WindR)
w.start()
w.menu()
library(quantmod)
getSymbols("IBM")

library(WindR)
> w.start()
[1] "Welcome to use WIND Quant API for R (WindR)!"
[1] "You can use w.menu to help yourself to create commands(WSD,WSS,WST,WSI,WSQ,...)!"
[1] ""
[1] "COPYRIGHT (C) 2013-2017 WIND INFORMATION CO., LTD. ALL RIGHTS RESERVED."
[1] "IN NO CIRCUMSTANCE SHALL WIND BE RESPONSIBLE FOR ANY DAMAGES OR LOSSES CAUSED BY USING WIND QUANT API FOR R."
$`ErrorCode`
[1] 0

$ErrorMsg
[1] "OK!"

> w.menu()
NULL
> library(quantmod)
> getSymbols("IBM")

到> library(quantmod)这一行都没问题，但是读取股票就不行了，为什么呢
