JMP Scripting Noob: How to input a new column based on filtering data from two columns?

[#1]

Hi all,

I love JMP for it's graph building tools, so I am just starting to dabble in the scripting portion of it. Can someone help me with this request?

I have two cols. One for X coordinate and one for Y coordinate. All I want to do is simply create a new col that will list Upper Right/Upper Left/Lower Right/Lower Left (LL)  based on the X and Y Coordinate...

So for example...

if 0<X<5 and 0<Y<5, label as LL

if 0<X<5 and 5<Y<10, label as UL

if 5<X<10 and 0<Y<5, label as LR

if 5<X<10 and 5<Y<10, label as UR

I am so lost, any help would be appreciated :)

You can fairly simply do this with Formulas in JMP by checking X and Y separately and concatenating them together.

Something like below should work (not that if the value is 0,5 or value over 10 it won't be categorized at all):

If(0 < :y < 5, "L", 5 < :y < 10, "U") || If(0 < :x < 5, "L", 5 < :x < 10, "R")

This can easily be done by finding which row has the different combinations of min and max values in the data table.

names default to here( 1 );
dt = New Table( "Sample",
	Add Rows( 4 ),
	New Column( "x",
		Set Values( [1, 1, 6, 6] )
	),
	New Column( "y",
		Set Values( [1, 6, 1, 6] )
	)
);

dt << new column("location", character, formula(
	:location[(dt << get rows where(:x==col max(:x) & :y==col max(:y)))[1]]="UR";
	:location[(dt << get rows where(:x==col max(:x) & :y==col min(:y)))[1]]="LR";
	:location[(dt << get rows where(:x==col min(:x) & :y==col max(:y)))[1]]="UL";
	:location[(dt << get rows where(:x==col min(:x) & :y==col min(:y)))[1]]="LR";
));
