Reorder by Descending order

> ggplot(EDAfilter, aes(x = EDAfilter$MCI, fill=as.factor(EDAfilter$MCI))) +
+     
+     geom_bar(width=0.8, stat="count") + theme(legend.position="none") + coord_flip() +
+     
+     ggtitle("Crime Records by Major Categories")

This was my code to understand the distribution of counts by categories. I want to reorder this by descending order i.e. top category for counts to the lowest. Below is the plot I got. Let me know how to reorder this. I tried using reorder but failing.

Thank you Andre. I shall keep this in mind for future posts. I found a work around for this using the dplyr package. Many thanks for your support. I shall come with more questions as I work on this project.

I think it's more convenient to count MCI yourself beforehand and then use geom_col() for your purposes. Reordering is done by fct_reorder

library(tidyverse)
EDAfilter %>% 
  count(MCI) %>% 
  ggplot(aes(x = fct_reorder(factor(MCI), n), y = n, fill = factor(MCI))) + 
  geom_col() + 
  theme(legend.position="none") + 
  coord_flip() +
  ggtitle("Crime Records by Major Categories")
