Error in levels<-(*tmp*, value = as.character(levels)) :
factor level [17] is duplicated
Looks like in the design phase of the survey, the same choices got entered more than once on different rows? I'm surprised SurveyMonkey allows that. At any rate, while a respondent now only sees ~20 choices for question 72351265, there are 164 (!) possible values stored in the levels, some of which appear twice. I'll resolve by calling unique on the possible values.
