Hey folks,
I have two arrays: "A" (1X100) with non-ordered values ranging 1-14
                         "B" (2X14)  containing 14 decimal values.
I would like to create a new array (1X100) that contains only the decimal values from array B by associating the integers from A and B. In other words, for each value of A find the same integer value of B, select the
associated decimal value of B.

Sounds like a job for merge(). Tested solutions offered when reproducible examples are provided.


A          B         newarray
1       1  0.1         0.1
1       2  0.3         0.1
1       3  0.14       0.1
2       4  0.2         0.3
3       5  0.82       0.14
3       6  0.21       0.14
4        .   .          0.2

14      .   .            .
