要剪切到預(yù)定義的間隔，可以使用breaks參數(shù)指定中斷的向量。
定義一些數(shù)據(jù)：
x <- sample(0:20, 100, replace=TRUE)x
現(xiàn)在在0,10和20處剪切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]

像這樣的東西？每個(gè)0.2從0到1中斷。
