How to vjust a label with a grouped bar chart of counts
I've got a grouped bar chart of count data, and would like to position the labels at the mid-point of each bar. However, I can't work out how to add a vjust statement into the position of the label - it keeps erroring with geom_text and stat_count. Any help would be amazing!
data <- data.frame(month = c(3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3,
3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4,
4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5,
5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5,
5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5,

This could be achieved by mapping ..count.. / 2 on y:
library(ggplot2)
ggplot(data, aes(x=factor(month), fill=factor(year))) +
geom_bar(stat="count", position = position_dodge2(preserve = "single"), colour="black") +
stat_count(geom = "text", colour = "black", size = 4,
aes(label = ..count.., y = ..count.. / 2), position=position_dodge(width=0.9))
