Question

每当我使用所有形式的getSymbols和get.hist.quote命令时，我都会收到错误。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 
    opened URL 
    downloaded 230 Kb 

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。我如何解决它？？顺便说一句，相同的命令在其他计算机上正常工作。使用的包：“quantmod”或“tseries”

运行我得到的评论中建议的调试器后：

> debugonce(read.table)
> getSymbols("AAPL")

感谢你的问题。我不能重现错误。我的文件正确下载并且读得很好。

my_file <- read.csv('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')

下载的数据无法在R中读取
