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)"
