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 ´íÎóÓÚdownload.file(paste(yahoo.URL, "s=", Symbols.name, "&a=", from.m, : ÎÞ·¨´ò¿ªURL'http://chart.yahoo.com/table.csv?s=APPL&a=0&b=03&c=2007&d=2&e=29&f=2014&g=d&q=q&y=0&z=APPL&x=.csv' ´ËÍâ: ¾¯¸æÐÅÏ¢£º In download.file(paste(yahoo.URL, "s=", Symbols.name, "&a=", from.m, : 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. [[alternative HTML version deleted]]
