I've never heard of the "yahoo.get.hist.quote" function, though its
documentation says it's in tseries (which it isn't). Though
tseries::get.hist.quote does exist.
I would recommend using quantmod's getSymbols function:
library(quantmod)
x <- getSymbols("0012.HK",auto.assign=FALSE)
Please note that you must turn off auto assignment because "0012.HK"
is an illegal object name because it starts with a number.
HTH,
Josh

Hello, everyone: I try to download the history data for a hongkong stock:0012.HK, using "yahoo.get.hist.quote", when I type the code:
library("UsingR")
instrument<-"0012.HK"
destfile<-"Henderson.csv"
yahoo.get.hist.quote(instrument,destfile,start=2008-1-1,end=2010-1-1,
+ quote="Close",download=TRUE,adjusted=TRUE,origin="1970-01-01", compression="d") there is an error message: Error in as.POSIXct.numeric(start, tz = "GMT") : 'origin' must be supplied I also try origin="1899-12-30", but the error message is still there. Did anyone encounter with this problem before ? Thank you very much for the help! ? ? ? ?[[alternative HTML version deleted]]
