# [R] Fuzzy_partition with fuzzy_trapezoid

```Thanks, Sarah, for response. But you showed me an example with
fuzzy_variable. I'd like to use fuzzy_partition. I also tried:

> teste = fuzzy_partition(varnames = c('a', 'b'), FUN = fuzzy_trapezoid, corners = c(1,2,3,4), height = c(1,1) )

But the trapezoids 'a' and 'b' were overlap. Is there a way to
construct two separeted trapezoids with fuzzy_partitions?
