EDIT
The original answer with pivot_wider is WRONG, I removed it. As suggested by @stefan in the comments, it dropped a row.A proper solution would include a preliminary step to add an index column, as already shown in @TarJae's answer, to which I should only add the simplification values_fn = ~ TRUE.The dummy_cols suggestion stands as a valid alternative
If a one-hot encoding/dummy presentation of values is OK (1s and 0s instead of logical), fastDummies::dummy_cols is nice too:
library(fastDummies)df |> dummy_cols('FRUITS', remove_selected_columns = TRUE, omit_colname_prefix = TRUE) Gender AgeGroup EAT Apple Banana1 Female 30yr_39yr Yes 1 02 Female 20yr_29yr Yes 1 03 Female 70yr_80yr Yes 1 04 Male 50yr_59yr Yes 0 15 Female 40yr_49yr Yes 1 06 Female 70yr_80yr Yes 1 0
