I am trying to create some dummy choices in collected data through an unlabeled CE in order to investigate sociodemographics that interact with choices. I am using the following code:
Code: Select all
database$choice_assistance=with(database,1*((choice==1)*(Att1==1)|(choice==2)*(Att1.1==1))
+2*((choice==1)*(Att1==2)|(choice==2)*(Att1.1==2))
+3*((choice==1)*(Att1==3)|(choice==2)*(Att1.1==3)))
choiceAnalysis_settings=list(alternatives=c(unit=1,call=2,routes=3),
avail=list(unit =with(database,1*(Att1==1)|(Att1.1==1)),
call =with(database,1*(Att1==2)|(Att1.1==2)),
routes =with(database,1*(Att1==3)|(Att1.1==3))),
choiceVar=database$choice_assistance,
explanators=data.frame(female=(database$gender==2),
lack_infrastructure=(database$lack_of_bike_infra==1)))
apollo_choiceAnalysis(choiceAnalysis_settings, apollo_control, database)
However, I am getting the following error:
Error in apollo_choiceAnalysis(choiceAnalysis_settings, apollo_control, :
The choiceAnalysis_settings list needs to include an object called "choiceVar"!
Any help will be really useful.
Thank you in advance.
