I'm not sure I understand. PerformanceAnalytics is part of the
"xts-family" (as opposed to the Rmetrics family) of finance packages.
Your problem may be that it requires returns, but consider this
(somewhat opaque) one liner.
charts.PerformanceSummary(ROC(Cl(to.weekly(Ad(getSymbols("IBM",auto.assign
= F))))))
which works just fine (using 3 packages explicitly and two major dependencies!)
