The presence of `zoo`, `xts`, and `IBrokers` in that list of non-attached namespaces seems unexplained. It's surely not a part of the standard base installation. `lattice` and `grid` are also not loaded by default so this suggests you have not completely removed all traces from the prior installation. Check to see that there isn't an .Rprofile or .Rdata still in the startup directory. (And delete them if there.)

I actually suggested reinstalling the R.app GUI using the binary installer at:
http://r.research.att.com/mavericks/R-3.3-branch/R-GUI-7238-3.3-mavericks-Release.dmg

I'm now wondering if it would be of value to instead install the Debug version:
http://r.research.att.com/mavericks/R-devel/R-GUI-7238-3.4-mavericks-Debug.dmg but that is a decision above my pay grade.
