[SOLVED] Is here someone can help me about operator pivot
Contributor I
1.my origin data like this:
FORMULA_ID HERB_ID
15 65
15 152
16 96
16 185
17 96
17 44
18 29
19 59
19 92
20 33
20 44
... ...
2.i want to use operator "pivot" to trans data("FORMULA_ID" as group attr,"HERB_ID" as index arrt) for next Association data mind.The attr "HERB_ID" has >50 different values,then the operator "pivot" can't work well,the resoult just can create only one regular attr which use the group attr.
while the "pivot" description say:
The resultant ExampleSet has m regular attributes in addition to the group attribute where m is the number of unique values of the index attribute.
Why?Dose there has any limit number of unique index attrs in the version of rapidminer?(My rapidminer version is 5.3.012 for student. ???)

You are missing one more attribute. The Group by attribute creates rows, Index attribute defines columns, and you miss what should be placed inside the exampleset after pivoting
For example you can do something like this: best Marcin
