Thank you Stephanie. I have requested the package be updated and will follow up if I still have this error after.
By the way, I noticed that the installation instructions in the latest version of the manual refer to 0.2.8.

- This forum is for questions related to the use of Apollo. We will answer some general choice modelling questions too, where appropriate, and time permitting. We cannot answer questions about how to estimate choice models with other software packages.
- There is a very detailed manual for Apollo available at http://www.ApolloChoiceModelling.com/manual.html. This contains detailed descriptions of the various Apollo functions, and numerous examples are available at http://www.ApolloChoiceModelling.com/examples.html. In addition, help files are available for all functions, using e.g. ?apollo_mnl
- Before asking a question on the forum, users are kindly requested to follow these steps:
- Check that the same issue has not already been addressed in the forum - there is a search tool.
- Ensure that the correct syntax has been used. For any function, detailed instructions are available directly in Apollo, e.g. by using ?apollo_mnl for apollo_mnl
- Check the frequently asked questions section on the Apollo website, which discusses some common issues/failures. Please see http://www.apollochoicemodelling.com/faq.html
- Make sure that R is using the latest official release of Apollo.
- Users can check which version they are running by entering packageVersion("apollo").
- Then check what is the latest full release (not development version) at http://www.ApolloChoiceModelling.com/code.html.
- To update to the latest official version, just enter install.packages("apollo"). To update to a development version, download the appropriate binary file from http://www.ApolloChoiceModelling.com/code.html, and install the package from file
- If the above steps do not resolve the issue, then users should follow these steps when posting a question:
- provide full details on the issue, including the entire code and output, including any error messages
- posts will not immediately appear on the forum, but will be checked by a moderator first. This may take a day or two at busy times. There is no need to submit the post multiple times.

Re: Non-overlapping choice sets
Thank you both for the responses! I didn't notice until now that you had replied. Before you responded, I also tested a slimmed down version of the model I was running using the two ways of coding, and confirmed that they yield equivalent results. Coding variables as an attribute seems to be useful ...

Non-overlapping choice sets
Hi Stephanie, I am just getting started on my journey with Apollo. I am working with a dataset where individual's choice sets depend on where they live and the year. For people in different areas / years, the choice sets are non-overlapping. Some people can choose between a handful of products, and ...
