   model: the model/formula to be parsed. This can be in either of two
          possible forms, one for 2d and one for 3d formulas,
          determined by the `dimension' argument. The 2d formulas are
          of the form `y~x|g_1*...*g_n', and the 3d formulas are of the
          form `z~x*y|g_1*...*g_n'. In the first form, `y' may be
          omitted. The conditioning variables `g_1, ...,g_n' can be
          omitted in either case. 

    data: the environment/dataset where the variables in the  formula
          are evaluated. By default, the environment where the function
          was called from. 

dimension: dimension of the model, see above
