dear all, I am trying to use an user-specified link function in glmer() (via the argument family), but the error is Error in famType(glmFit$family) : unknown link: ?my_link? my_link is a proper link function (of class "link-glm") which works correctly with glm() and also with MASS::glmmPQL() It appears that the function lme4::famType() checks for the name by comparing it with the names in "famNms" which includes "gaussian", "binomial", "Gamma", ... however I do not know whether it is sufficient to include "my_link" in famNms, and possibly I do not how to do it.. :-) many thanks, vito
