R geom_bar and facet_grid labels on top of bars

Question

I am trying to make this graph look better, and I\'m stuck with the labels (the numbers in this case). How can I make them to show on the top of their correspondent bar? Notice

You are almost there, just you need to move aes(fill=Gender) to inside ggplot

library(tidyverse)
#Reproducible data set
test_mtcars <- mtcars %>% group_by(cyl,am, gear) %>% summarise(mean = mean(mpg))

ggplot(test_mtcars, aes(as.factor(cyl), mean, fill=as.factor(am))) + geom_bar(stat = "identity", position = "dodge") + 
facet_grid(~gear) + geom_text(aes(label = round(mean, 2)), position = position_dodge(width = 0.9), vjust = -1)
