I'm not sure how to easily get that data from google (see Michael's
message), but it's available from yahoo.
getSymbols('TCS.NS', src='yahoo')
I've found that historical stock data from Yahoo is typically cleaner and
more reliable than from Google. The other main difference is that Yahoo
provides OHLCV and Adjusted columns, where the Adjusted column is the close
price series adjusted for dividends and splits. Google, does not provide
unadjusted or completely adjusted data. Instead, they give you data that
has been adjusted for splits, but not for dividends.
If you really want the yahoo data to look like google data, you could adjust
it for splits, and not for dividends like this
TCS <- adjustOHLC(TCS.NS, adjust='split')
HTH,
Garrett
p.s. If there is any reason to use historic stock price data from google
instead of yahoo, I would be very interested to hear it (off-list of course,
since it's off-topic)
