extracting random effects from model formula
Hi R-users
I would like to extract the random effects ("1|SITE", "1+SPECIES|SITE"
and "BA|SITE") from this model formula:
Full_model <- formula (VAR ~ (1|SITE) + (1+SPECIES|SITE) + (BA|SITE) +
HEIGHT + COND + NN_DIST)
I tried:
terms(Full_model)
labels(terms(Full_model))
but I could not distinguish between random and fixed effects.
thanks

factorial map?
hello! i'm dealing with the following: i've collected a factor
covariable at irregularly placed sampling points along a line with
spatial informations, i.e.: dataset<-c(x-coordinates, y-coordinates,
level-of-factor)
the factor describes the density of vegetation between 0 (no ground
cover) and 5 (almost complete cover). id like to produce a map similar
to the ones the akima package

compare results of glms
dear list!
i have run several glm analysises to estimate a mean rate of dung decay
for independent trials. i would like to compare these results
statistically but can't find any solution. the glm calls are:
dung.glm1<-glm(STATE~DAYS, data=o_cov, family="binomial(link="logit"))
dung.glm2<-glm(STATE~DAYS, data=o_cov_T12, family="binomial(link="logit"))
