Attempt to set an attribute on null
Closed this issue · 2 comments
I'm getting an "Error in setNames(k$text, k$answer_id) : attempt to set an attribute on NULL" error when I try to cast the Rmonkey response object as a data frame. It looks like one of my survey questions (It has a type of "label - maybe it's the button to go to the next page?) has a null $text value. Could that be an issue?
Here's my traceback:
g<-Rmonkey::getresponses(r,s[[1]])
as.data.frame(g)
Error in setNames(k$text, k$answer_id) :
attempt to set an attribute on NULL

9: sapply(i$answers, function(k) {
setNames(k$text, k$answer_id)
})
8: FUN(X[[i]], ...)

3: lapply(x, as.data.frame, details = details, ...)
2: as.data.frame.sm_response_list(g)
1: as.data.frame(g)
the response object looks something like this:
str(g[[1]])
