Question

经过一些调试后，我将问题缩小到以下几个方面：

  minc <- function(split, population, base, lift = 0.1) {
      control.pop <- population * (1- split)
      test.pop <- population*split

      control.cr <- base
      test.cr <- control.cr*(1+lift)

      #### print statements ####
      print(c(control.pop, control.cr))  # print values of variables
      print( rbinom(1, 5800.0 , 0.1)) # print rbinom for the values
      print( rbinom(1, control.pop, control.cr))  # print rbinom for the variables
    }


    minc(0.8, population = 29000, base = 0.1, lift = 0.1)

给出输出

[1] 5800.0    0.1
[1] 589
[1] NA

即我打印传递的变量的值，然后打印这些值的rbinom - 它工作正常 - 但是当我为变量做rbinom时，我得到NA。这里发生了什么？

Rbinom想要一个你可以做的大小的整数

control.pop <- round(population * (1 - split))

正如@ ben-bolker指出的那样使用.overlay { position: absolute; width: 100%; height: 100%; top: 0; left: 0; right: 0; bottom: 0; z-index: 1000; }会舍入到整数而不是截断：

为什么rbinom在R给我这里？
