如何将连续变量拆分为等长（定义的数字）的区间并仅在 R 中列出带有切点的区间？

Question

我想把一组数据分成四个大小相等的区间，例如：

x=c(0:10)

G1: [0,2.5)

G2: [2.5,5)

G3: [5,7.5)

G4: [7.5,10]

无论如何我可以将数据分成等长的间隔（在这种情况下说四个）并得到下面的列表，包括最小值和最大值：

0   2.5   5   7.5   10

谢谢！

Answer 1

您正在寻找 cut

cut(1:10, c(1, seq(2.5, 10, by=2.5)), include.lowest = T)
#  [1] [1,2.5]  [1,2.5]  (2.5,5]  (2.5,5]  (2.5,5]  (5,7.5]  (5,7.5]  (7.5,10]
#  [9] (7.5,10] (7.5,10]
# Levels: [1,2.5] (2.5,5] (5,7.5] (7.5,10]

如果您只想要均匀间隔的休息时间，请使用 seq

x <- 0:10
seq(min(x), max(x), len=5)
# [1]  0.0  2.5  5.0  7.5 10.0

Answer 2

data.frame(x, breaks=cut(x,breaks = 5, labels=c("1","2.5","5","7.5","10")) )

有用吗？（诀窍当然在 cut 函数中）
