[R-SIG-Finance] IBrokers - twsConnect error

[Jeff Ryan]

Hi Jonathan,

There is a new version of IBrokers on the way to CRAN.  This should
address the issue.

The CLIENT_VERSION needn't keep up btw.  The failure was coming from
the internal check for a match to the sent CLIENT_VERSION.  This was
never needed, and the connection has been refactored to have
connections be more robust.

Check CRAN in the next day or two.

Best,
Jeff
