Set value of a specific cell from other specific cell in a table


I have a table generate dby the node Scorer-The Accuracy value apears only on the third row. I want to copy this value to the first and second row.

For  example output of Scorer is:

Roo ID    TruePositive..........Accuracy    Cohenen

No           1559                         ?                   ?

Yes         1131                         ?                   ?

Overall    ?                             0.941           0.878


I want the value of the third row of Accuracy apears on the first two rows as well.


How i should do that?




You can use the Missing Value node to apply a "Most frequent value" replacement rule to the Accuracy column. Since you only have one value in the Accuracy column (the one on row #3), this value will be copied to both row #1 and row #2 in place of the missing ones.
