Chunk missing in Vignette

[Christian-T]

In the introductory vignette, one chunk seems to be missing. At the part "Getting data" it is not clear, how someone selects only two variables, and the third is still retained. I guess, it would be something like:

m3 <-  pisaUSA15[1:100, ] %>%
 select(broad_interest, enjoyment, self_efficacy) %>%
 estimate_profiles(3, select_vars=c("broad_interest","enjoyment"))
