Fill data table columns with values from another data table

[#1]

Hi JMP community,

I have a question regarding 2 data tables for which one of the data tables should have rows filled with values of columns from the other data table.

Here an example:

I have a data table (Table 1) which contains 2 columns that both have one value. In a second data table (Table 2) I have 2 columns with 9 values each. What I want is to copy the Result 1 and Result 2 column values of Table 1 to all 9 rows of Table 2. Can anyone help me correct this script? I'm using JMP 16.

Names Default To Here( 1 );

dt1 = New Table( "Table 1", 
	Add Rows( 1 ), 
	New Column( "Result 1", Numeric, Continuous, Set values( [3] ) ), 
	New Column( "Result 2", Numeric, Continuous, Set values( [5] ) ), 
);

val1 = dt1:"Result 1"n << Get values;
val2 = dt1:"Result 2"n << Get values;

dt2 = New Table( "Table 2" );

dt2 << New Column( "Test1", Numeric, Continuous, Set values( [1, 1, 1, 1, 1, 1, 1, 1, 1] ) );
dt2 << New Column( "Test2", Numeric, Continuous, Set values( [2, 2, 2, 2, 2, 2, 2, 2, 2] ) );
dt2 << New Column( "Result 1", Numeric, Continuous, <<Set each value( val1 ) );
dt2 << New Column( "Result 2", Numeric, Continuous, <<Set each value( val2 ) );

Hi,

I believe the reason the script above doesn't work is because the "<<Set each value" command requires a number as input, rather than a matrix; val1 and val2 are matrices.

One way to solve this is to change the last two lines accordingly:

dt2<<New Column( "Result 1", Numeric, Continuous,<<Set each value(val1[1]));

dt2<<New Column( "Result 2", Numeric, Continuous,<<Set each value(val2[1]));

Another way is to use "Set Values" by converting val1 and val2 into 9x1 matrices:

dt2<<New Column( "Result 1", Numeric, Continuous,<<Set values(J(nrows(dt2),1,val1)));

dt2<<New Column( "Result 2", Numeric, Continuous,<<Set values(J(nrows(dt2),1,val2)));

Thank you Hadley!  Your solution works perfectly!
