R help - Dec 2002 - lgamma(-0.8)=?

Dear R users:

I wonder anyone is aware of such a thing from lgamma()
> lgamma(-0.8)
[1] 1.747207

I thought it should be NA as in S-PLUS. Both R-1.3.1 and R-1.5.1
report this result. I don't have the latest R-1.6.1 so I don't
know whether this is corrected or not.

Happy holidays,
Paul.

lgamma returns the ln of the abs of gamma (see ?lgamma)

 > log(abs(gamma(-0.8)))
