How can i see all available data series from quantmod package?

H开发者_C百科ow to show which list of all quotes / data series available for example with getSymbols from Yahoo?

I don't know of a way. The TTR package has a function (stockSymbols) to download all the current symbols from the NYSE, AMEX, and NASDAQ. It tries to put them in an acceptable format for Yahoo, but there's no guarantee that the 6,000+ symbols it retrieves have data on Yahoo. I'm not sure what to do for other exchanges...

> library(TTR)
> x <- stockSymbols()
