useful in some unit tests. For example, it is useful in tests of factory classes where the test has to verify that a newly created object has the 31 expected dynamic type. It is also useful in managing the refactoring tools harder. First, the template code is expanded in multiple contexts, and it’s hard to verify that the transformation makes sense in all of them. Second, some refactoring tools work with an AST

graphics. The goal of the R Programming Style Guide is to make our R code easier to read, share, and verify. The rules below were designed in collaboration with the entire R user community at Google. Summary:

paper  Expected: same trend of baseline comparisons, parameter influence  #2 Reproducibility  Verify robustness of results wrt parameters and environments  Examples: different data and workload characteristics
