Question

Given a vector a=[1,2, 3.2, 4, 5] and an element x=3 In vector a, how to find the exact entry which is bigger than x? In R, is there any function to do that?

Answer 1

> a <- c(1,2, 3.2, 4, 5)
> x <- 3
> a[a > x]
[1] 3.2 4.0 5.0
> min(a[a > x])
[1] 3.2

Answer 2

the answer...

 min(a[a>3])
