Create your own statistcal functions
I want to create my own function that can calculate like Mean/Median/etc. does. So it has to calculate over the given set.
When I now use R in Transformation Flow, it calculates line by line. How could have an R function over the given set? (for instance to calculate quartile).
When creating a query (report) I can use the advanced functions and use the mean, median, etc. They calculate over the given set. Can I create my own functions like these? Is it also possible to see the code that is used to create these functions (like custom-functions.xml).
