下面是我的代码。我想要做的是下载股票和情节图表的多个符号，但我收到此错误：

library(quantmod)
stocks <- c("INFY.NS","HINDALCO.NS","TCS.NS","TATASTEEL.NS","NESTLEIND.NS",

Answer 1

问题是M&M.NS不是语法上有效的R名称（&具有特殊含义）。

library(quantmod)
getSymbols("M&M.NS")
chartSeries(M&M.NS)    # error
chartSeries(`M&M.NS`)  # use backticks for names that aren't syntactically valid

或者您可以使用setSymbolLookup()将符号映射到语法上有效的名称。然后，您可以在getSymbols()和chartSeries()来电中使用语法上有效的自动收报机。

setSymbolLookup(M.AMP.M.NS = list(name = "M&M.NS"))
getSymbols("M.AMP.M.NS")
chartSeries(M.AMP.M.NS)

在R中使用quantmod包修复错误时遇到问题：继承错误（x，＆＃34; xts＆＃34;）：对象＆＃39; M＆＃39;没找到电话
