add rows after selected rows

Pacco

Hello community,I am new to jmp and have troubles with creating a script that would add 1 row after each selected row within my dataset. Any ideas? My code looks like this so far:

dt=Current data Table ();
dt<<add rows(1,46030);

However, this of course adds a row only after the specified column. I selected my rows according to a sepcific name in one column and a sepcific value wihtin another column. How can I automatically enter a row after all my selected rows that are not adjacent but have unselected rows in between them?

Thanks in advance for your help!

Because the inserted rows will change the selected row numbers, the below modification to @uday_guntupalli script has to be made to actually get the results you want.

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Cities.jmp" );

dt << Select Randomly( 0.1 ); // Selecting rows randomly 

SR = dt << Get Selected Rows;  // Get list of selected rows 

For( i = 1, i <= N Rows( SR ), i++,
	dt << Add Rows( 1, SR[i] ); // Add 1 row after each selected row
	SR = dt << Get Selected Rows;
);

$SAMPLE_DATA

is an special environment variable for JMP. The structure of the OPEN() function is:

Open( file path, <invisible>, <private>, <select columns(list)> | <ignore columns(list)> )

See below, the Scripting Index for the Open

@Pacco,
Welcome to the JMP Community. Let me try and explain this and solve the problem. The Add Rows messge only specifies the # of rows and where to add so JMP is executing what the function is telling it to do. In order to scale it for your needs , we can try the following :

dt = Open( "$SAMPLE_DATA/Cities.jmp" );

dt << Select Randomly(0.1); // Selecting rows randomly 

SR = dt << Get Selected Rows;  // Get list of selected rows 

for(i = 1 , i <= N Rows(SR), i++,
		dt << Add Rows(1,SR[i]); // Add 1 row after each selected row
   );

Hope this helps and addresses your question

Thanks a lot, this script work perfectly for me.

The only thing I don´t understand, yet, is why my

dt<< open("$...");

function doesn´t work. I always have to use dt<< CurrentDataTable (); while having my table open already.

Thanks again for the valuable information!

dt<< open("$...");

is incorrect. The specified usage is

dt = Open(:$...");

It opens up the sample data table and assigns a handle to the openned data table called "dt";

dt = Current Data Table();

does the same thing as the Open() function, except it asigns to "dt" a pointer/handle to the current active data table.
