Question

I would like to check the elements of vector a is between the elements of vector b or not in R. How can I do this ? Means that is 3 between 2 and 4 and if yes appear in result, if not do not appear. Just mentiond that I dont want to check the first and last element of vector a. The result should be just 3.

      a = c(1, 3, 8, 12)
      b = c(0, 2, 4, 6, 8)

Answer 1

why don’t you just use a loop?

> a = c(1, 3, 8, 12)
> b = c(0, 2, 4, 6, 8)
> for (i in 2:(length(a)-1)){ if (b[i] < a[i] && a[i] <b[i+1]) {print (a[i])}}
