R – 按定义的间隔切割
R有没有一些方法可以在没有任何中断的情况下进行定义的时间间隔？
例如，如果我想要在确切的区间值[1,10]; 默认情况下会将这个间隔分成更小的间隔。
要剪切到预定义的时间间隔，可以使用breaks参数指定一个中断向量。
定义一些数据：
x <- sample(0:20, 100, replace=TRUE) x
现在在0，10和20剪下x：
cut(x, breaks=c(0, 10, 20), include.lowest=TRUE) [1] (10,20] [0,10] [0,10] (10,20] (10,20] (10,20] [0,10] (10,20] (10,20] [10] (10,20] [0,10] (10,20] (10,20] (10,20] [0,10] (10,20] [0,10] [0,10] [19] [0,10] (10,20] [0,10] [0,10] [0,10] (10,20] [0,10] (10,20] (10,20] [28] (10,20] (10,20] [0,10] [0,10] [0,10] [0,10] (10,20] [0,10] [0,10] [37] [0,10] [0,10] (10,20] (10,20] (10,20] (10,20] [0,10] (10,20] [0,10] [46] (10,20] [0,10] (10,20] (10,20] [0,10] [0,10] (10,20] (10,20] (10,20] [55] [0,10] [0,10] (10,20] [0,10] [0,10] [0,10] [0,10] (10,20] (10,20] [64] (10,20] [0,10] [0,10] (10,20] (10,20] (10,20] (10,20] (10,20] (10,20] [73] (10,20] [0,10] [0,10] [0,10] (10,20] [0,10] (10,20] [0,10] (10,20] [82] [0,10] [0,10] (10,20] [0,10] [0,10] [0,10] (10,20] (10,20] [0,10] [91] [0,10] [0,10] (10,20] (10,20] [0,10] [0,10] [0,10] [0,10] (10,20] [100] (10,20] Levels: [0,10] (10,20]
像这样的东西？ 每个0.2从0到1打破。
