Dear all,
I tried to apply the use of the set Analysis with "CLUSTERS" of data.
In specific, I attempted to make the union of two Clusters (1+2) and the difference (1-2)
I enclose an easy example that do not work propery
More in details, we have 4 items in the first cluster (Giacomo, Gianni, Giovanni, Leopardi) and 3 items in the second (Giacomo, Leopardi, Leopoldo)
Only two of them are in common. The first cluster has 2 elements not included in the second and the second cluster has 1 element not included in the first
The attemps is to create:
1) The INTERSECTION of the 2 clusters, using the operator "*". The example works and the result is 2 items (Giacomo, Leopardi).
The formula I used is:
sum( {<Nome=>*<FileDUE.Nome=>} FileDUE.StipendioDUE + StipendioUNO)
2) The UNION of the 2 clusters, using the operator "+". The result should be a list of 5 items (Giacomo, Gianni, Giovanni, Leopardi, Leopoldo), but it DOES NOT WORK
The formula I used is:
sum( {<Nome=>+<FileDUE.Nome=>} FileDUE.StipendioDUE) + sum( {<Nome=>+<FileDUE.Nome=>} StipendioUNO)
2) The DIFFERENCE of the 2 clusters, using the operator "-" (Cluster 1 - Cluster 2). The result should be a list of all the elements included in the first cluster that are not in common: 2 items (Gianni & Giovanni).. , but it DOES NOT WORK
The formula I used is:
sum({<Nome= {}> - <FileDUE.Nome = {}>} StipendioUNO)
Could someone help me to sort out this issue?
Thanks
Alberto
