从 R 导入股息时出错

Question

我正在尝试从 R 导入股息。有些股票有错误，我不知道它们是什么意思。

以下是我使用的代码：

library(quantmod)


mdate <- "2016-01-04"
edate <- "2016-09-03"

Tick <- c("FAM","FCT","FEI","MAIN","WSR","ERF","ETB","ETG","ETJ","ETV","ETW",
          "ETX","ETY","EVG","EVN","EVT","EXG","KIO","MNE","MNP","MPA","MQT",
          "MQY","MTR","MTT","MUA","MUB","MUC","MUE","MUH","MUI","MUJ","MUNI",
          "MUS","MVF","MVT","MYC","MYD","MYF","MYI","MYJ")
  

Dividend_160104 <-
  lapply(Tick,
         function(x) {
           try(getDividends(x, from= mdate, to= edate, src="yahoo"),
               silent = TRUE)
         })
names(Dividend_160104) <- Tick

随着符号，从第19个是“MNE”开始，出现错误； “open.connection（文件，“rt”）中的错误如果我运行只有几个符号，没有错误，但我有三千多个符号。几天前，我格式化了我的硬盘并在我的移动硬盘中重新安装了 R。是因为这个吗？有人知道为什么会这样吗？

Answer 1

这在一定程度上与对雅虎无效的代码有关。 MNE 不是有效的代码，会报错。由于此问题会影响股息的获取方式，因此此处的错误也会导致以下代码失败。

有关详细信息，请参阅 github issue 314。在撰写本文时，开发人员正在处理此问题。
