Yes, I'm willing to pay for it, but I would like to get it automatically into a format I can parse and use, not even sure where that exists at the moment. (Doesn't Yahoo Finance get their data...

Hello, New to working with deSolve and rootSolve and ran the example under runsteady and tried to determine the time to reach steady state but despite all my attempts to manipulate the 'istate' or 'rstate' values to match the plot...

Brian, Isn't any stream of cumulative returns, de facto, an equity curve? Or am I misunderstanding this? Thanks, Ralph Vince ----- Original Message ----- From: "Brian G. Peterson" <brian at braverock.com> To: "Aleks Clark" <aleks.clark at gmail.com> Cc...

I used dev.off(). I am certain that the problem is associated with acrobat reader. Seeing that my collaborators use primarily acrobat reader it looks like I'm stuck with this limit. Thanks for the help. Vince Marc Schwartz wrote...

I'm downloading certain equity data from yahoo on an eod basis, using the code, below. It works wonderfully, formatting the data and dates precisely as I am looking for EXCEPT often the data is late. Often, the latest market...
