Have you read the docs? Is this some kind of homework? -- this list does not do homework. We expect minimal efforts at least on the part of posters. We do not do tutorials here. I think you need to do some reading on your own before posting further. Try posting on the r-sig-mixed-models list to

[R] Linear Mixed-Effects Model

Dear R Help: What does "lmer(responce ~ factor1*factor2 + (factor1*factor2 | group1) + (factor1*factor2| group2), data)" mean? And "lmer(responce ~ factor1*factor2 + (factor1*factor2 | group1) + (factor1*factor2| group2), data)" vs. "lmer(responce ~ factor1*factor2 + (factor1+factor2 | group1)

[R] Linear mixed effects model ?

I am looking for some advice on an appropriate statistical analysis in R *Experimental question* : We are interested in how communities from different streams may vary in their response to experimental temperature. Specifically we are interested to test for differences in the slope and
