Question

csv文件：

"Date","","","","","",
"2014-01-03",1832.98,1838.24,1829.13,1831.37,0,1831.37
"2014-01-06",1831.37,1837.16,1823.73,1826.77,0,1826.77
"2014-01-07",1826.77,1840.1,1828.71,1837.88,0,1837.88
"2014-01-08",1837.88,1840.02,1831.4,1837.49,0,1837.49

命令：

> getSymbols("SPX3",src="csv")

> SPX3:

           SPX3.Open SPX3.High SPX3.Low SPX3.Close SPX3.Volume
2014-07-23   1832.98   1838.24  1829.13    1831.37           0
2014-07-23   1831.37   1837.16  1823.73    1826.77           0
2014-07-23   1826.77   1840.10  1828.71    1837.88           0
2014-07-23   1837.88   1840.02  1831.40    1837.49           0
           SPX3.Adjusted
2014-07-23       1831.37
2014-07-23       1826.77
2014-07-23       1837.88
2014-07-23       1837.49

因此，除了日期之外，它已正确加载所有内容。谁知道为什么？顺便说一句，这个问题和这个人有同样的问题（Date error while reading csv file into getSymbols），但是没有解决方案。

Answer 1

使用setSymbolLookup指定应从CSV中读取SPX3并确保format正确无误。

require(quantmod)
setSymbolLookup(SPX3=list(src="csv",format="%Y-%m-%d"))
getSymbols("SPX3")

Quantmod没有通过getSymbols从csv中读取日期
