问题描述

我需要使用cut函数将不规则的中断划分为不规则的中断。

I need to use the cut function to divide into irregular, uneven breaks.

我需要将剪切范围划分为1至15、16至19、20至45 ...等虽然我不知道该怎么做或是否可能。

I need to cut into ranges such as 1 to 15, 16 to 19, 20 to 45... ect. Though I do not know how to do this or if it is possible. Please help!

推荐答案

？cut 是很好的第一步。 。

?cut is a good first step...

以下是您可以构建的示例：

Here is a sample from which you can build:

# create a long vector that you want to cut
z <- rnorm(10000)
# create a vector with irregular breakpoints
breaks <- c( -6, -1, 1, 3, 6 )
# cut the long vector, look at the `table()`d result
table( cut( z, breaks ) )
  (-6,-1]  (-1,1]   (1,3]   (3,6] 
     1572    6806    1608      14
