R - 정의 된 간격으로 자름

Question

정의 된 간격으로 끊기지 않고 R을 자르는 방법이 있습니까?

예를 들어 정확한 간격 [1,10]의 값을 원하면; 기본적으로 cut은이 간격을 더 작은 간격으로 나눕니다.

Answer 1

미리 정의 된 간격으로 자르려면 breaks 매개 변수를 사용하여 끊김 벡터를 지정할 수 있습니다. 이 같은

cut(x, breaks=c(0, 10, 20), include.lowest=TRUE)

Answer 2

뭔가 : 0, 10, 20에서

x <- sample(0:20, 100, replace=TRUE) 
x 

이제 잘라 X :
