In R, if you test a condition on a vector instead of a scalar, it will return a vector containing the result of the comparison for each value in the vector. For example…
> v <- c(1,2,3,4,5)
> v > 2
[1] FALSE FALSE TRUE TRUE TRUE
In this way, I can determine the number of elements in a vector that are above or below a certain number, like so.
> sum(v > 2)
[1] 3
> sum(v < 2)
[1] 1
Does anyone know how I can determine the number of values in a given range? For example, how would I determine the number of values greater than 2 but less than 5?
