Error when calculating Individual Proportions on default (stan) branch. No stan files?

[jimjunker1]

Hello authors:

I have been recently working to estimate diet contributions with combined SI and FA on the stan branch. The models run well when calculating 'Population.proportions', however, fail on both 'Individual.proportions' or 'Analysis.with.Covariates' with the error:

Error in (function (classes, fdef, mtable) :unable to find an inherited method for function ‘sampling’ for signature ‘"NULL"’

Upon inspection, I believe this arises when setting up the model as the stanmodels object does not contain stan files for these routines.

Am I understanding the issue correctly or am I missing something?

If I am understanding this correctly, is this a work in progress? Or is there a workaround?

Thank you for your time and effort with this package.

Cheers.

Hi Jim -

yes, unfortunately I never got around to doing the indiv. proportions in Stan. I had some funding to get me to the current point, but haven't had any more funds to work on this since...

The old JAGS branch may still work, but it's pretty old by now so it may be hard to get going.

sorry to not have better news on this!
cheers
Phil

Hi Philipp,

Thank you for your reply and for your work putting the package together. Unfortunate, but completely understandable.
I was able to run the JAGS branch for individual proportions without issue, as far as I can tell. Thank you for this recommendation. All the best,
Jim
