In stefvanbuuren/dsMice: DataSHIELD server-side functions for the mice package

Description Usage Value See Also Examples

This helper function attempts to find blocks of variables in the specification of the formulas and/or predictorMatrix objects. Blocks specified by formulas may consist of multiple variables. Blocks specified by predictorMatrix are assumed to consist of single variables. Any duplicates in names are removed, and the formula specification is preferred. predictorMatrix and formulas. When both arguments specify models for the same block, the model for the predictMatrix is removed, and priority is given to the specification given in formulas.
