error with isospace plot and compare models

[shannonfinn8]

Hi,

I adapted the alligator script to use with my own data set on bears. I keep encountering errors, the first one appears after I attempt to create the isospace plot, "Error in grid.Call.graphics(C_text, as.graphicsAnnot(x$label), x$x, x$y, : Metric information not available for this family/device",

I also get an error message after I run the models and try to compare them with compare_models, "Error in compare_models(jags.mod) : x is not a list of 'rjags' models. Retry using e.g. 'compare_models(x=list(jags.1, jags.2))'."

The mod object gets created but does not seem to actually have model information within. Each model states they are type NULL.

I went back to try run the alligator script again and see if I could shed some light on this, however I get the same errors using this script and provided example dataset.

Any idea where I am going wrong ? I have an updated version of R Studio installed (4.1.0).

Thank you
