“每个"的值不止一个“rep"中的参数功能? [英] More than one value for "each" argument in "rep" function?

问题描述

如何为 R 中的rep"函数中的每个"参数分配一个以上的值?一个简单的例子，其中向量中的每个值在一行中重复 3 次:

How to assign more than one value for "each" argument in "rep" function in R? A trivial example, where each value in a vector is 3-times repeated in a row:

a <- seq(2,6,2)
rep (a,each = 3)

但是，如果我在each"参数中添加多个值以更改每个值的重复次数，则无法正常工作:

However, if I add more than one value in "each" argument in order to change the number of repetition of each value, it doesn't work properly:

rep (a, each = c(2,4,7))

如何解决?先感谢您.

推荐答案

根据您认为输出应该是什么，我猜您需要 times= 参数:

Depending on what you think the output should be, I'm guessing you want the times= parameter:

rep (a, times = c(2, 4, 7))
# [1] 2 2 4 4 4 4 6 6 6 6 6 6 6

区别见?rep
