PerformanceAnalytics package
This is most likely a conflict between xts/zoo and the various f* Rmetrics packages (or possibly the timeSeries package from Rmetrics). You'll like see a warning that function 'time' is being masked. the zoo/xts and Rmetrics teams are aware of the issue, and are trying to sort out a modle that will avoid trhe conflict. For now, the most likely way for you to avoid this issue is to not load the Rmetrics packages, or to load zoo/xts *after* you've loaded any Rmetrics packages you need.

hi,
I've been trying to familiarize myself with the PerformanceAnalytics
package.
As I go through the examples (in the attached file), I faced a hiccup.
When I run the following code, it only prints the first chart
charts.PerformanceSummary(managers[, c(manager.col,
indexes.cols)],colorset = rich6equal, lwd = 2, ylog = TRUE)
and gives me the following error:
Error in UseMethod("time<-") :
no applicable method for 'time<-' applied to an object of class
"c('xts', 'zoo')"
Can you please let me know how I can fix it.
Thanks!
