R - 按定义的间隔切割

Question

R - 按定义的间隔切割

在R中是否有某种方式可以在没有任何中断的情况下按照定义的间隔进

例如，如果我想要精确区间[1,10]中的值; 默认情况下cut，将此间隔分成较小的间隔。

Answer 1

要剪切到预定义的间隔，可以使用breaks参数指定中断的向量。定义一些数据：x&nbsp;<-&nbsp;sample(0:20,&nbsp;100,&nbsp;replace=TRUE)x现在在0,10和20处剪切x：cut(x,&nbsp;breaks=c(0,&nbsp;10,&nbsp;20),&nbsp;include.lowest=TRUE) &nbsp;&nbsp;[1]&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;(10,20]&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;(10,20] &nbsp;[10]&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;(10,20]&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp; &nbsp;[19]&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;(10,20] &nbsp;[28]&nbsp;(10,20]&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp; &nbsp;[37]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;(10,20]&nbsp;(10,20]&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;[0,10]&nbsp; &nbsp;[46]&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;(10,20]&nbsp;(10,20] &nbsp;[55]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;(10,20] &nbsp;[64]&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;(10,20]&nbsp;(10,20]&nbsp;(10,20]&nbsp;(10,20]&nbsp;(10,20] &nbsp;[73]&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;(10,20] &nbsp;[82]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;(10,20]&nbsp;[0,10]&nbsp; &nbsp;[91]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20]&nbsp;(10,20]&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;[0,10]&nbsp;&nbsp;(10,20][100]&nbsp;(10,20]Levels:&nbsp;[0,10]&nbsp;(10,20]

像这样的东西？每个0.2从0到1中断。>&nbsp;a&nbsp;<-&nbsp;runif(100)>&nbsp;cut(a,&nbsp;seq(from&nbsp;=&nbsp;0,&nbsp;to&nbsp;=&nbsp;1,&nbsp;by&nbsp;=&nbsp;0.2)) &nbsp;&nbsp;[1]&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.6,0.8]&nbsp;(0.6,0.8]&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0.6,0.8] &nbsp;&nbsp;[8]&nbsp;(0.2,0.4]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.4,0.6]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.4,0.6]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.6,0.8] &nbsp;[15]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.6,0.8]&nbsp;(0.6,0.8]&nbsp;(0.2,0.4] &nbsp;[22]&nbsp;(0.4,0.6]&nbsp;(0.6,0.8]&nbsp;(0.2,0.4]&nbsp;(0.6,0.8]&nbsp;(0.6,0.8]&nbsp;(0.6,0.8]&nbsp;(0,0.2]&nbsp;&nbsp; &nbsp;[29]&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0.2,0.4]&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0,0.2]&nbsp;&nbsp; &nbsp;[36]&nbsp;(0.6,0.8]&nbsp;(0.2,0.4]&nbsp;(0.6,0.8]&nbsp;(0.6,0.8]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.2,0.4]&nbsp;(0.4,0.6] &nbsp;[43]&nbsp;(0.4,0.6]&nbsp;(0.6,0.8]&nbsp;(0.2,0.4]&nbsp;(0.6,0.8]&nbsp;(0.6,0.8]&nbsp;(0.6,0.8]&nbsp;(0.4,0.6] &nbsp;[50]&nbsp;(0.6,0.8]&nbsp;(0.6,0.8]&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0.2,0.4]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.8,1]&nbsp;&nbsp; &nbsp;[57]&nbsp;(0.6,0.8]&nbsp;(0.2,0.4]&nbsp;(0.2,0.4]&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.2,0.4] &nbsp;[64]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.2,0.4]&nbsp;(0.4,0.6]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0.4,0.6]&nbsp;(0,0.2]&nbsp;&nbsp; &nbsp;[71]&nbsp;(0.4,0.6]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.6,0.8]&nbsp;(0.4,0.6]&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0.2,0.4]&nbsp;(0.4,0.6] &nbsp;[78]&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0.2,0.4]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0.4,0.6]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0,0.2]&nbsp;&nbsp; &nbsp;[85]&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0.2,0.4]&nbsp;(0.2,0.4]&nbsp;(0.4,0.6]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.2,0.4]&nbsp;(0,0.2]&nbsp;&nbsp; &nbsp;[92]&nbsp;(0.6,0.8]&nbsp;(0.2,0.4]&nbsp;(0.2,0.4]&nbsp;(0.8,1]&nbsp;&nbsp;&nbsp;(0.2,0.4]&nbsp;(0.4,0.6]&nbsp;(0,0.2]&nbsp;&nbsp; &nbsp;[99]&nbsp;(0,0.2]&nbsp;&nbsp;&nbsp;(0,0.2]&nbsp;&nbsp;Levels:&nbsp;(0,0.2]&nbsp;(0.2,0.4]&nbsp;(0.4,0.6]&nbsp;(0.6,0.8]&nbsp;(0.8,1]
