How do I split a big data table into smaller ones? (un-merge or opposite of concatenate)

tejvishnu — Sun, 30 Apr 2017 23:29:41 GMT

Hi,

Is there a script or a function which would essentially do the opposite of the "Concatenate" function? I have a massive data file with a source column which is the primary key & other columns associated with each primary key. I am trying to split this massive data table into several smaller tables based on the primary key.

Any suggestions?

Thanks

The easiest way to do this is to use the Subset with the "Subset By" selection

I tried it and it worked perfectly. Thanks a bunch!

I must confess I am bit embarrassed that for as long as I have been using JMP (especially the "Subset" function) I did not even notice the "By" checkbox.

I remember using JMP 3, and with the breadth and depth of JMP, I learn new JMP functionality all the time.
