R help - Apr 2009 - extract tables as data.frames from HTML source

Hi,

I wonder whether there is any convenient function (or package) to
extract tables from a HTML page? e.g. from
http://www.google.com/finance/historical?q=SHE:002251

I know we can readLines('URL'), gsub('<td>...',
'...', source), ...
and at last get the numbers; I'm writing to ask whether someone has
already contributed a more general function (with the package XML or
other packages). Thanks!

Regards,
Yihui

Try a search on R (I prefer markmail search)

If the question is specific to getting stock data from
google finance then check out getSymbols.google
in the quantmod package.

Also note that there exists an r-sig-finance list for questions
pertaining to R and finance.
