Hello @Pedro87
There are a couple of solutions already discussed and shared in the Forum:
-
the KNIME component by @Residentstiefel
IRR Calculation with KNIME - #11 by Residentstiefel -
The R script solution that I shared:

PS.- The file that you shared is showing own names, and if no mock names it would be breaching some data protection regulations.
I would suggest to use encrypting techniques for the private data and rewrite the post again. This one could be kindly removed by the admin team if you will.
