Repeated mesaures mixed model in R

Manuel Spínola-2
Dear list members,

I am fitting a repeated measures mixed model in R.

I have a response variable (continuous) with 4 treatments.  Each treatment
has 4 plots, and each plot was divided in 4 subplots.  The variable was
measured 5 times (occasions).

My attempt is:

mod <- lmer(response variable ~ occasion * treatment + (occasion |

Is the model parameterization correct?
