我使用quantmod的函数getQuote获得了对一堆股票的最后报价。我尝试使用* .MI形式的符号，并获得他们的报价没有任何问题。但是，当处理* .MC形式的代码时会出现错误，尽管符号和信息存在，例如可以通过VIS或EBRO看到。有谁知道API中包含的信息是否与网站上显示的信息不同？有没有人知道如何克服这个问题？
library(quantmod)
# note than VIS is a different equity than VIS.MC
getQuote('VIS.MC', what='b2')
getQuote('EBRO.MC', what='b2')
答案 0 :(得分：1)
目前，可能无法通过yahoo finance API下载西班牙语交易所的报价。
在评论部分here中搜索“MC”会产生：

I understand that ALL stock quotes from the spanish exchange are not available.
my feeling is that spanish quotes are available on payment, so Yahoo cannot make them available free of charge.
if you get the historical prices, no problem at all.
I am not sure to have solved your problem, but it is the same problem I faced some time ago.
另外，here：

Dear Hector,

因此，当'VIS.MC'符号存在但不能下载时出现错误：
