I posted this on SO, got no response. Sorry about cross-posting, but atleast I would like to know if I am understading something totally wrong I am using a `glmulti` wrapper for glmer (binomial) and the `summary` is: `This is glmulti 1.0.7, Apr. 2013. Length Class Mode 0 NULL NULL` Following what has been done on this this thread, though this is for `lmer`, <http://stackoverflow.com/questions/12228418/glmulti-runs-indefinitely-when-using-genetic-algorithm-with-lme4>, I get the same result as above. Could it be that the versions have changed since and the wrapping has to be done differently? The following is the dummy code (lifted form the link above): xd = as.factor(round(runif(30),1))# dummy grouping factor yind = runif(30,0,10) # mock dependent variable ad = runif(30) # dummy covariate bd = runif(30) # another dummy covariate cd = runif(30) # an another one dd = runif(30) tmpdata <- data.frame(xd=xd,yind=yind,ad=ad,bd=bd,cd=cd,dd=dd) lmer.glmulti <- function (formula, data, random = "", ...) { lmer(paste(deparse(formula), random), data = data, REML=F, ...) } summary(glmulti(formula = yind~ad*bd*cd*dd, data = tmpdata, random = '+(1|xd)', level = 2, method = 'h', crit = 'aic', marginality = TRUE, fitfunc = lmer.glmulti)) `lme4` version: 1.1.5 `glmulti` version: 1.0.7 "R version 3.0.2 (2013-09-25)" -- View this message in context: http://r.789695.n4.nabble.com/glmulti-wrapper-for-lmer-does-not-produce-results-tp4688463.html Sent from the R help mailing list archive at Nabble.com.
