Lambda.R introduces types as an alternative to classes. Types are data structures with type information attached to it. Like classes, constructors exist for types and one type can inherit from another type. The difference is that types do not have embedded methods. In functional programming, fun...
本章最后一节介绍了purrr包,平时用到的函数式编程的功能都汇集起来了,使得具体干活的时候,非常快,代码易读不易错。(具体用来做data science的, R for Data Science一书一定要反复读,这书有网站,可以直接看)第六章使用所谓的point-free来介绍函数组合,这个也是函数式编程的鲜明特色,在实际数据处理和建模的时候会相...

and you’ll construct complex functions using simpler functions as building blocks. In Functional Programming in R, you’ll see how we can replace loops, which can have side-effects, with recursive functions that can more easily avoid them. In addition, the book covers why you shouldn't use...
Chapter 1:介绍Functional Programming(FP)和C++世界的结合 Chapter 2:高阶函数(函数具有值语义);标准函数库中的应用 Chapter 3:C++中的可调用对象(常规C函数、函数对象、lambda表达式等) Chapter 4:柯里化,从旧函数创建新函数的方式 Chapter 5:不可变数据(immutable data)的重要性 Chapter 6:深入理解惰性计算(laz...
Functional programming (FP) is a paradigm in where a program is composed of functions. A function is a building block that encapsulates a computation. A function applied with a value, always returns the same computed value. FP avoids mutating state. FP allows developers to create powerful proces...
