Hi,
 
I wrote a lme that goes like this:
 
f9 <- lme(masse ~ jour + annee + site + sexe + site*annee, random=~1+jour|phoque, data=data3)
 
 
masse : seal mass, continuous
jour : seal age at capture (days); numeric and continous (range from 1 to 34)
annee : year where data was collected, factor of 4 levels (2008-2011)
site : capture site, factor of 2 levels 
sexe: seal sex, factor of two levels (male, female)
phoque: seal individual (random effect)
 
There is two things I want to know:
 
First, I want to know wether any of the parameters have significant effects and the importance of these effects. I already did this and selected the model with the lowest AIC. This model is the one I wrote above.
 
The second and the most important point is that I want to obtain some "basic" informations about my dataset. I want to use my model to determine certain generalities like:
 
What is the growth rate (slope of the regression) of the males in general (in terms of mean and SE)?
What is the birth mass (mass at day 1) of the females in 2010 (also in terms of mean and SE)? 
 
Is there a special command in R that could help me do that?
 
Thank you,
