Rstudio 错误 Quandl "code":"QECx02","message"

Question

我正在尝试从 Quandl 导入财务数据

library(Quandl)
library(xts)

currencies <- c("RUB", "USD", "JPY", "EUR", "CNY")
currencies <- paste("CURRFX/BRL", currencies, sep= "")

currency_ts <- lapply(as.list(currencies), Quandl, start_date="1999-01-01", end_date="2014-12-30", type="xts")

我已经用其他货币尝试过几次并且确实有效，但突然停止工作并开始给我这种错误:

Error: {"quandl_error":{"code":"QECx02","message":"You have submitted an incorrect Quandl code. Please check your Quandl codes and try again."}}

Answer 1

尝试使用具有 getFX、getSymbols 和 getFinancials 等功能的 quantmod 包... This 网站还列出了使用 R

访问财务数据的不同包

Answer 2

我认为当代码正确但在开始日期没有可用的 quandl 数据时也会显示此消息。
