R 编程语言广泛用于统计计算。为了实现交互式数据探索和快速原型设计，R 鼓励动态编程风格。这种编程风格得到一流环境等功能的支持。在广泛使用的语言中，R 具有最丰富的用于以编程方式操作环境的接口。由于一流环境中的反射操作所提供的灵活性，推理和优化用户定义代码面临着巨大的挑战。本文记录了用于在一流环境中运行的反射接口。我们解释了其设计背后的基本原理，并对如何在流行的图书馆中使用该界面进行了大规模研究。
The R programming language is widely used for statistical computing. To enable interactive data exploration and rapid prototyping, R encourages a dynamic programming style. This programming style is supported by features such as first-class environments. Amongst widely used languages, R has the richest interface for programmatically manipulating environments. With the flexibility afforded by reflective operations on first-class environments, come significant challenges for reasoning and optimizing user-defined code. This paper documents the reflective interface used to operate over first-class environment. We explain the rationale behind its design and conduct a large-scale study of how the interface is used in popular libraries.
