how to keep a partly duplicated sample

aileenzhou

I have a dataset, there are some duplicated DOI. I must keep one of the duplicated DOIs based on 'source' attribute with preference: A>B>C, and delete rest.
For example, the data below, I want to keep row 1261 and 643, delete the rest. 

Row        DOI                      Source
18           10.1002/67           B
1261       10.1002/67           A
1400       10.1002/67           C
...
...
643        10.102/et.67         A
1428      10.102/et.67         C

Thank you in advance.

Hi @aileenzhou,

If I good understand, one way to do that is to : 

 - Reorder attributes (1/ Source , 2/ DOI)
 - Generate concatenation (via Generate Aggregation attribute)
 - Sort alphabetically the concatenated attributes (via Sort attribute / sorting direction = increasing)
 - Remove duplicates of this concatenated attribute.
 - Split back the concatenated attribute to retrieve the original attributes (without the duplicates)

Take a look at the attached process and tell me if it answer to your need ...

Regards,

Lionel

@lionelderkrikor Thank you sooooo much. What if source 'B' is preferable records to keep?
