Solution

Or this using the DIF function:

New Column( "lgs",

Numeric,

Continuous,

Formula( Dif( :lg, 1 ) )

)

If you are working interactively you can just create a new column and use the formula builder to enter the formula Dif(:lg, 1)

I am using bivarate plot and adding a fit line. I would like to save slope and intercept values in a text file. I am using following code:

biv=rbiv<

show(Ex1);

Show(Ex1) show the value of slope in the log file along with the log of entire session. Is it possible to send JSL command to save the values of just slopes and intercepts in to a new data table or seperate text file from the log.

Thank you

Regards,
