每当我使用所有形式的 getSymbols 和 get.hist.quote 命令时,都会出现错误。错误基本上是:
>getSymbols("AAPL")
Error in read.table(file = file, header = header, sep = sep, quote = quote, :
more columns than column names
另一个例子:
>x <- get.hist.quote(instrument = "^gspc", start = "1998-01-01", quote = "Close")
trying URL 'http://chart.yahoo.com/table.csv?s=^gspc&a=0&b=01&c=1998&d=4&e=12&f=2013&g=d&q=q&y=0&z=^gspc&x=.csv'
Content type 'text/csv' length unknown

Error in read.table(destfile, header = TRUE, sep = ",", as.is = TRUE, :
more columns than column names
所有来源和符号都在发生这种情况。我如何解决它??顺便说一句,相同的命令在其他计算机上工作得很好。使用的包:“quantmod”或“tseries”
运行评论中建议的调试器后,我得到:
> debugonce(read.table)
> getSymbols("AAPL")
