At the moment I don't think there are tests for:
- offsets parameter
- weights parameter
- the different ways of expressing a model formula, that is:
'BMI ~ age, data = 'D'
D$BMI ~D$age
BMI_vector ~ age_vector where the variables are not in a dataframe but in separate vectors
- formulae with a
+ 1 or + 0
I think this would help trap potential errors
