latticeParseFormula(model, data, dimension = 2)
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 |
