[R-SIG-Finance] PerformanceAnalytics - small problem with Return.excess

[Giuseppe Milicia]

Guys,

I've noticed a small problem in PerformanceAnalytics, Return.excess does not like timeseries with only 1 elements. Obviously this situation does not happen often, but getting around the issue is rather unelegant:

Loading required package: PerformanceAnalytics

Package PerformanceAnalytics (1.0.2.1) loaded.
