r - 相当于SAS企业矿工评分节点的R是多少？

Question

SAS Enterprise Miner 有一个称为“分数代码节点”的东西。该节点将所有先前的代码(即创建新变量、输入缺失值以及运行模型等)应用于完全未触及的数据集。除了使用保留样本(即测试数据)之外，如何在 R 中执行此操作？

Answer 1

使用 Rattle GUI，如论文中所述:

The underlying R code, constructed and executed by Rattle, is recorded in the Log tab, together with instructive comments. This allows the user to review the actual R commands. The R code snippets can also be copied as text (or Exported to file) from the Log tab and pasted into the R console and executed. This allows Rattle to be deployed for basic tasks, yet still access the full power of R as needed (e.g., to fine-tune modelling options that are not exposed in the interface).
