[R-SIG-Finance] Fwd: Problems with charts.PerformanceSummary

When I try to run example(charts.PerformanceSummary) I get an error
message. I think there is some sort of incompatibility with the data
type and the drawdown part of the command. Maybe the locale?

Any clues would be greatly appreciated....

Many thanks in advance,

chr.PS> data(edhec)
