Deleting columns

Anonymous — Tue, 10 Apr 2012 01:27:24 GMT

I am creating a bunch of new columns in a jmp datasheet and generate a summary table. I am doing all of this as a JMP script. Then I delete the new columns manually, exclude certain rows based on values in a column (manually) and rerun the earlier script. Is there a way to have jmp delete specific columns and exclude specific rows for me, as a script, instead of doing it manually?

Thanks,

Ravi

Something like this should work: (though it may be more complicated depending on the condition you're using to exclude rows)

dt = data table("Your Table Name");
 
dt<< delete column(column("1st Column to Delete"));
dt<< delete column(column("2nd Column to Delete"));
 
dt<<select where(/*condition for excluding*/);
 
dt<<exclude;
