Say I have a numeric vector as in X = 1:10000. Is there currently a way in R to obtain a list of 10 intervals from X as shown in my Desired_output?

Desired_output = list(c(0,1000), c(1001,2000),  c(2001,3000),  c(3001,4000),  c(4001,5000),  
                      c(5001,6000), c(6001,7000), c(7001,8000), c(8001,9000), c(9001,10000))

CodePudding user response：

Use seq

Map(`c`, c(0, seq(1001, 10000, by = 1000)), seq(1000, 10000, by = 1000))

-output
