Check if multiple column values fall within range

hooshies — Tue, 22 Sep 2015 17:27:00 GMT

Sample table:

Part	Test 1	Test 2	Test 3	Test 4
A	0.2	0.4	0.3	0.1
B	0.2	0.3	0.4	0.6
C	0.7	0.1	0.2	0.4

I would like to add a column to this table that evaluates every value in columns Test 1-Test 4, and if all fall within a range to output "Yes".

For example, if my range was 0 < values < 0.5, the output would look like this (I've highlighted failing values in red)

Part	Test 1	Test 2	Test 3	Test 4	Yes/No
A	0.2	0.4	0.3	0.1	Yes
B	0.2	0.3	0.4	0.6	No
C	0.7	0.1	0.2	0.4	No

Is there a simple way to achieve this with JSL?

hi hooshies,

to answer your exact question the following script can do it.

A more general solution depends on the aspect that needs generalizing (i.e. more columns, different ranges for different columns and whether you want it in a column formula or just to be calculated once by jsl)

dt = New Table( "Data source",

Add Rows( 3 ),

New Column( "Part", Character, Nominal, Set Values( {"A", "B", "C"} ) ),

New Column( "Test 1", Set Values( [0.2, 0.2, 0.7] ) ),

New Column( "Test 2", Set Values( [0.4, 0.3, 0.1] ) ),

New Column( "Test 3", Set Values( [0.3, 0.4, 0.2] ) ),

New Column( "Test 4", Set Values( [0.1, 0.6, 0.4] ) ),

);

dt << New Column( "Yes/No",

Character,

Nominal,

Formula(

If(

Maximum(

Abs( :Test 1 ),

Abs( :Test 2 ),

Abs( :Test 3 ),

Abs( :Test 4 )

) > 0.5,

"No",

"Yes"

)

);

Ron,

Thanks for you response. The script you provided gets the job done in this situation, but I would like a more robust/general solution (for example, when the limits of my testing criteria are 0.23 < test values < 0.5).

Is there a way to set a column formula or script a solution where multiple columns are treated as an array? In pseudocode:

lower_limit = 0.23

upper_limit = 0.5

If lower_limit < [Column(2), Column(3), Column(4), Column(5)] < upper_limit

disp "Yes"

Else

disp "No"

The pseudocode here would test each value in columns 2-5 individually against the limits, and output "Yes" if all are in range.

Multiple AND/OR statements would achieve this, but seems like an elementary approach.

Thanks!

ron_horne's method can be generalized. The key is to recognize that the Minimum() and Maximum() functions return the min/max value of their arguments. So, as you pose it, the comparison it can be written:


Minimum( :Test 1, :Test 2, :Test 3, :Test 4 ) > 0.23 &

Maximum( :Test 1, :Test 2, :Test 3, :Test 4 ) < .5;

New Column("In Range?", Formula(

If(

Min( :Test 1, :Test 2, :Test 3, :Test 4 ) > 0 &

Max( :Test 1, :Test 2, :Test 3, :Test 4 ) < 0.5,

"Yes",

"No"

)
