Re: [R-SIG-Finance] Delete bad dividend row
Hi Garret, That did help. I've been analyzing dividend yields and the quantmod getDividends and getSymbols work flawlessly. But then the dividends change frequency over time, special dividends creep in and now a spurious data point for PM. So far I've dealt with these with your help and others.

[R-SIG-Finance] Delete bad dividend row
Hi all, I successfully get dividend data from Yahoo Finance, including a bad dividend: 2012-12-20 0.039 How do I delete this one row from the data? This dividend shows up on the Yahoo Finance site but is not reported by Philip Morris.
