How to Get as Matrix

[#1]

I am wondering if anyone knew how to get as matrix with specific row.

For example, I would like to get as matrix with row(1),

mat will be [12 59 95].

Names Default To Here( 1 );
bigclass=Open( "$SAMPLE_DATA/Big Class.jmp" );
mat = bigclass << GetAsMatrix({2,3::5});
Show(mat);

mat =
[ 12 59 95,
 12 61 123,
 12 55 74,
 12 66 145,
 12 52 64,
 12 60 84,
 12 61 128,
 12 51 79,
 13 60 112,
 13 61 107,
 13 56 67,
 13 65 98,
 13 63 105,
 13 58 95,
 13 59 79,
 14 61 81,
 14 62 91,
 14 65 142,
 14 63 84,
 14 62 85,
 14 63 93,
 14 64 99,
 14 65 119,
 14 64 92,
 14 68 112,
 14 64 99,
 14 69 113,
 15 62 92,
 15 64 112,
 15 67 128,
 15 65 111,
 15 66 105,
 15 62 104,
 15 66 106,
 16 65 112,
 16 60 115,
 16 68 128,
 17 62 116,
 17 68 134,
 17 70 172];

Here is one way to do this:

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/big class.jmp" );
dt << delete columns( {name, sex} );
valueMatrix = dt[1, 0];

Show( valueMatrix );

Depending on what else you are doing, you could also use data table subscripting:

mat2 = bigclass[1, {2, 4, 5}]
