Competition model

[shuyi yang]

Dear Facundo,

Thanks a lot for your great efforts on breedR package.

Now I would like to use the competition model in breedR for my research. When fitting a competition model in the "genetic" effect, "pedigree" is a necessary element. However, I work on half-sibling and all the parents for these progeny are unknown. I spent a lot of time trying to figure this issue; however, I failed. Does it mean I couldn't apply the competition model on my dataset? Do you have any idea on dealing with such issue?

Thanks in advance for your help.

Best regards,

Zoe
