Hello Jeff,

First, thanks very much for providing a very useful library.

Wasn't aware of them, thanks.

When getOptionChain() quit working (no thanks to OCC+Yahoo), the first
thing I did was go to:

http://www.quantmod.com/download/

and use the command:

> install.packages(c('xts','Defaults','quantmod'))

That didn't help, and the suggestion on the above page:

========================================================================
For the latest version of quantmod (and TTR) - download the source here:

    xts package source:     xts_0.0-15.tar.gz
    quantmod package source:     quantmod_0.3-6.tar.gz
    TTR package source:     TTR_0.14-0.tar.gz 
========================================================================

didn't seem likely to improve the situation, since
quantmod_0.3-6.tar.gz is quite old.

Thanks to your mention of R-forge, I used:

> install.packages("quantmod", repos="http://R-Forge.R-project.org")

and that upgraded from the 0.3-13 I was using to 0.3-14, which
fixed the problem.

Thank you very much for the help.
