Re: How to use JMP script to generate a table with duplicate data

Try this:

dt = Current Data Table();
Ntimes = 5;
for(i=1,i<=Ntimes,i++,
	dt << Concatenate (dt, Append to first table(1));
);

Re: How to use JMP script to generate a table with duplicate data

Nice! if you want N copies rather than doubling the size N times, you can start with an empty table like this:

dt = Current Data Table();
Ntimes = 5;
dtnew = New Table();
For( i = 1, i <= Ntimes, i++,
	dtnew << Concatenate( dt, Append to first table( 1 ) )
);

The empty table is special when first created: it appears to have a column named "Column 1", but that column is a placeholder that will vanish if not used.

Doubling with Tom's answer is much faster if you need a lot of copies. 10 doubles in 0.02 sec or 1024 copies in 0.50 sec.
