Hello, I have built a linear mixed model (with lmer).  To illustrate an interaction between 
two (originally) continuous variable, I would like to plot the effects of X1 versus Y for 1=low and 2=high X2. I am using plotLMER.fnc but have not been able to figure out the code. Could you help?
Thanks, Ulla
