Hi R,
I am a new Chinese user of R, I like this language very much.In the
recent months,I spend over 4 hours every day leanring R,but during the learning
I come across some problems I can not understand.For R is still not very
popular in China,I ask some net friends but nobody can give me a satisfactory
answer,so I have to ask for your help. In the package quatmod, getSymbols is a
useful tools to fetch datas form the Internet but it often can not work when I
use it,such as
getSymbols("APPL",src="yahoo") or
getSymbols("APPL",from="2007-01-03",to=Sys.Date()) .It should be useful because
many books have already shown it ,but As of 0.4-0, ¡®getSymbols¡¯ uses
env=parent.frame() and
auto.assign=TRUE by default.
This behavior will be phased out in 0.5-0 when the call will
default to use auto.assign=FALSE. getOption("getSymbols.env") and
getOptions("getSymbols.auto.assign") are now checked for alternate defaults
This message is shown once per session and may be disabled by setting
options("getSymbols.warning4.0"=FALSE). See ?getSymbol for more details

ÎÞ·¨´ò¿ª: HTTP״̬ÊÇ'404Not Found'
I want to know why.Maybe it due to the damn Great Firewall. I hope you can
reply to me when convenience. Best ragards.(My English is not fluent, please do
not mind)
A Chinese R user & lover.
