quantmod getSymbols.csv 的日期问题？

Question

我正在使用 quantmod 函数将文件上传到 R getSymbols.csv。然而，一旦我上传了文件，日期似乎丢失了，所有的日期都是一样的。

我使用以下代码上传 100 个股票代码：

getSymbols.csv(symbols, env=parent.frame(), dir="E:/data/CData_Files_NB/", 
           return.class = "xts", extension="csv")

所有的都上传了，但是对于每个股票代码，整个历史的日期是相同的？？

  [97] "APFJ"    "ILVJ"    "DBXUSJ"  "WEZJ"

这是我的意思的一个例子。所有日期都加载为相同的（最后一个）日期？

我错了什么？它可能与 CSV 文件中的格式有关，还是与时间序列 xts 或 zoo 类有关？任何帮助将不胜感激。
