| Title: | Translate R Regression Model Formulae to 'Julia' Syntax |
|---|---|
| Description: | Metaprogramming utilities for converting R regression model formulae to equivalents in 'Julia' <doi:10.1137/141000671>, via modifications to the abstract syntax tree. Supports translations in zero correlation random effects syntax, protection of expressions to be evaluated as-is, interaction terms, and more. Accepts strings or R formula objects and returns modified R formula objects where possible (or a modified string, if not a valid formula in R). |
