R help - Sep 2008 - fBasics package: dnig

Hi,

I am trying to calculate probability density of normal inverse gaussian
distribution. I am using dnig function of fBasics package. However, I am getting
following result. The density at x = 0.003042866 is:
> dnig(x= 0.003042866, alpha=5.184868, beta= 0.11841, delta= 0.06038513, mu=
-0.0003520626)
[1] 6.550251 


I am not sure why it is 6.550251. Can anyone tell me why density is more than 1?
Thank you for your time.

Without looking closer at the specific distribution: Why shouldn't it be 
more than 1? The density at x=0.25 of a uniform(a=0, b=0.5) distribution 
is 2 - hopefully.
