Examples

rel <- data.frame(
    sets = c(rep("A", 5), "B", "C"),
    elements = c(letters[seq_len(6)], letters[6])
)
TS <- tidySet(rel)
TS <- activate(TS, "elements")
size(TS)
TS <- activate(TS, "sets")
size(TS)
# With fuzzy sets
relations <- data.frame(
    sets = c(rep("A", 5), "B", "C"),
    elements = c(letters[seq_len(6)], letters[6]),
    fuzzy = runif(7)
)
TS <- tidySet(relations)
TS <- activate(TS, "elements")
size(TS)
TS <- activate(TS, "sets")
size(TS)
