## Copy rows and change one column value

I'm finding the row documentation very frustrating. Is it possible to copy an entire row and add it to the current data table? My rows have many columns so I do not want to go through every column name doing this.

Alternatively, if it's possible to make a single one-way graph from two different data tables, then this will also solve my problem. Does JMP have that capability?

## Re: Copy rows and change one column value

Here's an example that uses Big Class.  I make a subset table using row 8, and then append it back to the original Big Class table.

dt1 = open("\$sample_data/Big Class.jmp");

// Make a subset using row 8
dt2 = dt1 << Subset( Selected Rows( 0 ), Rows( [8] ),
Selected columns only( 0 )
);

// Concatenate the new table back to big class
dt1 << concatenate(dt2, append to first table);
