library(quantmod)

setSymbolLookup(SZZS=list(name="000001.SS", src="yahoo"))
getSymbols("SZZS")

getSymbols(Symbols = NULL,  #股票代码,例如'000001.SS', 'CHL', 'APPL'

env = .GlobalEnv,
reload.Symbols = FALSE,
verbose = FALSE,
warnings = TRUE,
src = "yahoo",
symbol.lookup = TRUE,
auto.assign = TRUE,
...)

还可以指定from='2013-01-01', to=''

candleChart(), chartSeries(), barChart(), lineChart()均为画图

默认multi.col=FALSE,为绿橙色. 如果为TRUE,则为红灰色,不好看.

参数up.col='red', dn.col='green'

 

showSymbols(env=.GlobalEnv)

显示当前已有的股票

removeSymbols(Symbols=NULL,env=.GlobalEnv)

saveSymbols(Symbols = NULL,
file.path=stop("must specify 'file.path'"),
env = .GlobalEnv)
