Working with Models: , and ,, of R packages that support this is well beyond the scope of this book. The main concerns when choosing and fitting models is not the syntax, and this book is, after all, a syntax reference. We will look at two packages that aim at making a tidy interface to models.HUMP 发表于 2025-3-27 08:01:09

Functional Programming: ,,A pipeline-based approach to data processing necessitates a functional programming approach. After all, pipelines are compositions of functions, and loops and variable assignment do not work well with pipelines. You are not precluded from imperative programming, but you need to wrap it in functions.Digest 发表于 2025-3-28 12:07:33
