pars option for fixef, ranef, and coef?

[peterphalen]

Hello!

I'm trying to run calculations on the posterior samples of the random effects of a large varying-slope / varying-intercept model. For bureaucratic reasons I'm currently forced to use brms on a government computer that has limited RAM and freezes up when it has to manipulate matrices that are too large. So, calling coef(summary=FALSE) on the full model is not practical, but I think the machine could handle coef(summary=FALSE, pars="smaller_set_of_coefficients").

Would it be possible/easy to add a pars option to the fixef(), ranef(), and coef() functions?

Thank you so much!
Peter

I like this idea. In the new github version of brms, you can now select coefficients via pars.
