[R] glmulti wrapper for lmer does not produce results
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)

[R] convert multi dimensional array to list
I have an 4D named array (the result of recast() on a dataframe) and would like to convert it to a list with the names retained. Example: my.df-expand.grid(name=c(Alf,Que), month=c(May,Jun), year=c(2011,2012)) my.df$tmax-sample(15:20,4) my.df$tmin-sample(10:15,4) my.df.melt=melt(my.df) my.df.cast=cast(my.df.melt, year~name~month~variable) I want to convert it to a list so I can access the elements by name like my.df.cast$tmax$May to get the corresponding year-name matrix This assuming, lists provide an easier way to handle this data. Does it? Also, may be there is a way to get the list I want from my.df without going through the melt and cast. Any suggestions are welcome. Thanks in advance Anto PS: I came across threads for converting list to array but not the other way round. -- View this message in context: http://r.789695.n4.nabble.com/convert-multi-dimensional-array-to-list-tp4645011.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] convert multi dimensional array to list
Hi Michael thanks! That was the option if I kept it an array. The list format with $ sign since it leaves me feeling that the names are there and can be easily accessed. Why would you rather not use the $ sign? I use R-Studio and there names can be selected from a drop-down list, I have found it easier but that could be my lack of proper training in R.

[R] subsample clustered data
Hi all I am pretty new to R and would like some help concerning subsampling my data. I have got locations of species presence that are clustered in some regions of my study area. using this for habitat modelling produces overfitting the denser areas. I would like to subsample the presence location. Ideally, something like create a buffer zone around the points, then randomly select only one of the points within if there is more than one inside the buffer.

[R] selecting random points within a buffer
helloo let me try rephrase my previous post this way. I have a distribution of points ( with cords) and I want to select only or two points that fall within a buffer distance from each point. I guess there should be some way to do this in R. Can someone help or suggest where I might find a solution?
