[R] ANOVA model

[Street N.R.]

Hi,

Could someone tell me if this is the correct model syntax for the
following dataset:

lme(height~treatment+genotype+treatment*genotype,drought,random=~genotyp
e)

The dataset has two factors: one fixed - treatment, and one random -
genotype. I need to test the effect of both factors to identify their
significance. There are multiple (but not equal) replicates at each
level of genotype (the replicates are independent biological samples).

What I need are the p values for genotype, treatment and their
interaction. It is the specification of the random factor that I am
unsure of.

Also, does anyone know if biologists 'expect' to see type I or type III
SS results presented in a standard (i.e. non statistical) journal
article?

Thanks in advance
