Other Add-In Functions

A secondary purpose of this add-in is to allow the user to add their own Custom Functions by simpling adding an entry to the table provided.


To open the Conversions table, simply click on Add-Ins -> Conversions -> Open Conversions Table...




To add your own function, simply follow the format as the previous entries in the table. If you want to create your own namespace for new functions, simply change the name from "Conversions" in the current row you are working in to what you want it to be. This will create your own scripting index and formula category within JMP.





After adding your function to the table, click on Add-Ins -> Conversions -> Update Scripting Index / Formulas, to add your new functions into the scripting index and forumla sections. 




All formulas should now appear in both the scripting index and formula section!


Formula Editor




Scripting Index




Another capability of this add-in is the ability for a user to create a brand new table to separate their own Custom Functions from the Conversions Tables Custom Functions. If you want to do this, simply follow the format and naming convensions of the Conversions table when creating a new table. Make sure the new table you are working on is saved in the same location as the "Conversions Table" (This should be located in your "...\JMP\addins\\" folder OR wherever your addin is saved...).



** Note: If you want to delete a formula from the table and have it take place in the Scripting/Formula areas, you must restart JMP after deleting the entries and saving the table.
