Hello,

   I'm a Masters student at UC Davis and I'm trying to use R to produce a
linear mixed effect model for my data on N2O emissions in agricultural
ecosystems. I'm looking at the effects of management practices (such as
fertilization and irrigation) as well as crop type, soil type, and other
environmental factors on N2O emissions in California cropping systems.
However, I'm having trouble finding specific examples on how to do it. I've
never used a computer program like this before and I'm struggling on where
to begin. Do you have any advice or specific examples that could point me in
the right direction?

Thanks,
Gina
