Difference of fct_reorder and reorder

问题

This is an exmaple of fct_reorder

boxplot(Sepal.Width ~ fct_reorder(Species, Sepal.Width, .desc = TRUE), data = iris)

This code is identical with boxplot(Sepal.Width ~ reorder(Species, -Sepal.Width), data = iris)

What is the better point fct_reorder() than reorder()?
