统计编程语言 R 中的默认编程是否可行？

Question

是tacit programming also known as point-free style - an option in R吗？

Answer 1

检查 magrittr package since it seems closest to what you are asking. Wikipedia 引用示例：

For example, a sequence of operations in an applicative language like the following:
def example(x):
   y = foo(x)
   z = bar(y)
   w = baz(z)
   return w
...is written in point-free style as the composition of a sequence of functions, without parameters:

def example: baz bar foo

在 magrittr 的 R 中可以写成

x %>% foo %>% bar %>% baz

其中 %>% 运算符用于组成函数链，以便将前一个函数的输出作为后续函数的第一个参数传递。请参阅 magrittr 小插图以了解更多信息。

可以定义函数

# explicitly
example <- function(x) x %>% foo %>% bar %>% baz

# or simply (as @bergant noticed)
example <- . %>% foo %>% bar %>% baz
