[R-sig-ME] Mixed Models

[Neil French Collier]

Hi Jessica,

It's likely that you don't have enough data to fit the model you described.
These are more like stats questions (i.e. what factors to include), but I
think if you provide more information about your problem (A reproducible
example) then you might get more help. See here for how to do this:

Cheers,

Neil
