Hi Jurgen,
sorry to bother but I just noticed that the argument ordered in the function plot_coef is not working as expected.
I am using the latest camtrapR version available on CRAN.
My code was
myplot.area.coef <- plot_coef(object = mod.jags,
mcmc.list = out,submodel="state",ordered=FALSE)$area
and the resulting plot

I have also tried to re-arrange the output of the function using this line of code where mylist.species.coef is a vector with the species names sort by alphabetical order
#order the species by name
myplot.area.coef$data <- myplot.area.coef$data[match(mylist.species.coef,as.character(myplot.area.coef$data$species)),]
and although the data are now sorted alphabetically, the plot is still not right.
Any hints on how to overcame this issue?
Regards,
Stef
