Good morning,

>dput(m2)
structure(c(9822616000, 3841723000, 79790.09, 3841723000, 1502536000, 
31251.82, 79790.09, 31251.82, 64156419.36), .Dim = c(3, 3))

> det(m2, method="eigenvalues")
[1] -9.331893e+19
> det(m2, method="qr")
[1] 9.331893e+19

I hope it's not just some numerical accuracy thing and therefore
wasting your time.

Thx,
	Armin
