问题
I can use quantmod to get historical data and close-to-realtime quotes for stocks. I can also use quantmod to get financials data from Google. Are there any existing R packages that would let me grab Google's news feed for a given stock?
If not, is there a package for reading and parsing RSS feeds in R?
回答1:
Sure, RSS is after all XML, so use the XML package.
回答2:
There's also a (not yet on CRAN) package that does some of the nitty gritty of parsing RSS feeds (and Atom) for you - nothing fancy, just some of the basic cleaning, normalization between the RSS and Atom spec, etc.
You can grab it from https://github.com/noahhl/r-does-rss
(full disclosure, I wrote it)
回答3:
I wrote my own function to do this, using XML and xts. I posted it as a question on SO, because I think it could be improved.
