I'm getting an error whenever I call stdev() on a vector with one element. Is stdev() really not equipped to deal with this edge case? Any clever work arounds?

I see the following msg:
Vector must have size > 1
Seems fairly reasonable. If this is an "edge case" then so would be the sound of one hand clapping. Is "standard deviation of a single sample, or of a set that contains only one member" a zen exercise, or does it have an accepted meaning?

Hahaha, great response, I see your point.
