Between two numbers in R i.e. 57

Question

am just trying to find a way to identify numbers in a data set that fall between two values. What i have done so far is to use ifelse i.e. ``` ifelse(score<=5,1,ifelse(score<=7,2,3)) ``` and this has worked but I want to know if you guys know a better method of finding say 5<=R>7, thanks James

`findInterval` is almost what you want, but has open right sides to the intervals. Inverting by negating everything in sight gives closed-right-side intervals. Your code: ``` x <- function(score) ifelse(score<=5,1,ifelse(score<=7,2,3)) ``` A `findInterval` approach: ``` y <- function(score) 3 - findInterval(-score, -c(7,5)) ``` Results: ``` > x(1:20) [1] 1 1 1 1 1 2 2 3 3 3 3 3 3 3 3 3 3 3 3 3 > y(1:20) [1] 1 1 1 1 1 2 2 3 3 3 3 3 3 3 3 3 3 3 3 3 ```
