Chategorical variables only

shiny
1

Hello,
I'm doing a Shiny App where the user introduce some data frame and can do some data analysis.
I wonder if there is a way in wich, for example, in a selectInput there are only show the chategorical variables of that data.

Thank you

#example_data
(hiris<-head(iris))

#old way - still works and fine to use
select_if(hiris,
          is.factor)

#new way
select(hiris,
       where(is.factor))
