programming: telling a function where to look for the entered variables
...s. My problem is that
I'm not quite sure how to tell my function in which dataframe the
entered variables are located.
Here's some reproducible data and the function:
# create reproducible data
set.seed(124)
xvar <- sample(0:3, 1000, replace = T)
yvar <- sample(0:1, 1000, replace=T)
zvar <- rnorm(100)
lvar <- sample(0:1, 1000, replace=T)
Fulldf <- as.data.frame(cbind(xvar,yvar,zvar,lvar))
Fulldf$xvar <- factor(xvar, labels=c("blue","green","red","yellow"))
Fulldf$yvar <- factor(yvar, labels=c("area1","area2"...

ZIB models
...for him is no
longer in service.
Hopefully someone can help.
I'm using obs.error in R to model turtle occupancy in wetlands.
I have 4 species and 20 possible patch and landscape variables, which
I've been testing in smaller groups.
> zib.out<-obs.error(y=painted,m=numvis,bp=zvars,pcovar=7)
I get the following error message, with all species, all variable
groups, standardized and unstandardized data...
Error in optim(par = rnorm(pcovar + qcovar), fn = obs.error.LL, method =
"L-BFGS-B", :
L-BFGS-B needs finite values of fn

dynamically creating functions in r
it is possible to dynamically create functions in R using lists? what I want
to do is something like this:
a = list()
for (i in 1:10) a[[i]] = function(seed = i) runif(seed)
so that when I call a[i] I get random draws 1,2,....i unfortunately R only
uses the last i . I would also like to know if there is a run-all function
without explicitly looping or using lapply. for example if I
