[R] A question on Statistics

[Jeff Newmiller]

You should use Stack Exchange for questions about statistics.

You should also think a bit before you post, regardless of where. You are 
the one who described this as a highly asymmetric distribution, and didn't 
say anything about it being centered at zero. You already answered your 
own question, to the extent that it can be answered.
