ApolloChoiceModelling forum

Looking a bit further, the issue seems to be with my use of 'summary' instead of 'apollo_modelOutput'. Works fine when I use this to examine the results.

Hi John,

Unlike most R packages, Apollo doesn't use "summary" to print an estimated model to screen, but instead its own apollo_modelOutput function. We'll try to allow the use of summary in future releases, but for now remember using apollo_modelOutput instead.

Thanks, particularly for your test code, which is what lead me to see what was going on.
