> getSymbols('^SSEC',from='2011-01-01',to='2012-07-13') #getSymbols函数自动连接Yahoo数据源，读取的数据源是SSEC（上证指数Yahoo的代码），时间范围从2011-01-01到2012-07-13
‘getSymbols’ currently uses auto.assign=TRUE by default, but will
use auto.assign=FALSE in 0.5-0. You will still be able to use
‘loadSymbols’ to automatically load data. getOption("getSymbols.env")
and getOption("getSymbols.auto.assign") will still be checked for
alternate defaults.
