I agree and R2admb makes that possible. Posted the example to show how model.matrix can be used to help generalize the tpl and automate the model generation process. Presumably reading in text files isn't too slow. Is there an option to read in binary files if there is a large amount of input data? regards --jeff <br>

I will not judge what is right or wrong, but here are my simple preferences<br>
over the past 10 years:<br>
1. Communicate between R and ADMB via textfiles, e.g. R2admb<br>
2. Do as much as possible of the pre and post processing in R. Hence<br>
model.matrix() belongs on the R side.<br>
