[R] returning parameter values by CoCo

[assuncao.senra@portugalmail.com]

Hello,
as anyone used CoCo?
I used 'backward' function to find a loglinear model for my data, wich I did. 
Now I´m trying to get the estimates of the parameters of the model. I 
tried 'returnExpression' but I can´t understand the output. Besides the same 
model I get the value TRUE.
Can someone explain me?
Thanks in advance.
