Comparing row values

powerpuff — Wed, 14 Mar 2018 21:20:09 GMT

I have a table which has 2 columns Term and Multiply which looks something like this:

I want to somehow be able to read the column "Term" and check the following:

1) If the term in the "Term" column is not multiplied by anything (like Name, Place, Animal and Thing in the above table), then multiply the value in the "Multiply" column by 2.

2) If the term in the "Term" column is multiplied by any other term (like Place*Thing in the above table), then multiply the value in the "Multiply" column by 2.

3) If the term in the "Term" column is multiplied by itself(like Name*Name and Animal*Animal in the above table), then keep the value in "Multiply" column as it is.

The resulting table would look like this:

Can this be done using jsl? Thanks

Maybe something like this:

New Table( "Multiply",
	Add Rows( 8 ),
	New Column( "Term", Character, "Nominal",
		Set Values( {"Name", "Place", "Animal", "Thing", "Name*Name", "Place*Thing",
			"Animal", "Animal*Animal"} )
	),
	New Column( "Multiply", Numeric, "Continuous",
		Format( "Best", 12 ),
		Set Values( [0.43, 0.5567, 0.056, 0.236, 0.15503, 0.44479, 0.7789, 0.22754] )
	),
	New Column( "Result",
		Expression,
		"None",
		Formula(
			mtch = Regex Match( :Term, "([^*]*)\*([^*]*)" );
			If(
				N Items( mtch ) == 0, :Multiply * 2,
				N Items( mtch ) == 3,
					If( mtch[2] == mtch[3],
						:Multiply,
						:Multiply * 2
					)
			);
		)
	)
)
