making a new wave with certain values another wave

Hi forum,

I have a for loop that outputs distances between points and calls them wave R (R0 up to R5). Now in each wave R has values lets say

R15

0
9.0062
17.6678
27.0128
36.1731
46.5191
8.97521
15.6237
23.8978
9.20011
42.8077
18.3848
 

For each wave R , I want to make a new wave that includes values between 7 and 11, so for this example, it would make a wave DataSortedR15 with three elements :,

9.0062

8.97521

9.20011

I know some sort of if loop is needed. How to do so?

Thank you in advance
