我如何(最好使用R)如何从Yahoo.Finance，Google Finance或其他工具获取股票行情清单的行业分类.为了说明这一点，我列出了一些行情自动收录器，例如

How can I (preferably using R) get the industry classification for a list of stock tickers from Yahoo.Finance, Google Finance or anything else. To illustrate, I have a list of tickers, such as

ticker_industy <- data.frame(ticker=ticker_list,industry=rep(NA,length(ticker_list)
head(ticker_industry)
    ticker industry
1      BDX       NA
2      BLL       NA
3       CB       NA
4     CELG       NA
5      CHK       NA
6       CI       NA

最好，R为每个股票获得相应的行业.

Preferably, R fetches the corresponding industry for each ticker.
