[R-sig-ME] Mixed model for compositional data

Hi all,

I have repeated measures of individual diet composition (I actually have 
the number of each item eaten and the duration of each observation) and 
I would like to model the effect of variables such as season and 
moonlight on diet composition (not the actual number of item eaten).
I gathered that I should use compositional but the packed 'compostions' 
doesn't allow the inclusion of random factors.

Does anyone has experience whit such data and analyses and point me in 
the right direction?

Thanks a lot in advance for your replies!
