Hello everybody.
I have an "esthetic" question. I have managed to create a stacked and
grouped bar plot but I don't manage with putting the text in the middle of
the bar plots. Do you know how to write the numbers in that position?
Thank you so much.
Example code:
test <- data.frame(variables = c("PE_35", "PE_49"),
value1=c(13,3),
value2=c(75,31),
value3=c(7,17),
value4 =c(5,49))
library(reshape2) # for melt
melted <- melt(test, "variables")
melted$cO <- c("A","A","B","B","A","A","B","B")
melted$cat <- ''
melted[melted$variable == 'value1' | melted$variable == 'value2',]$cat <-
"0"
melted[melted$variable == 'value3' | melted$variable == 'value4',]$cat <-
"1"
names(melted)[3] <- "recuento"
library(ggplot2)
ggplot(melted, aes(x = cat, y = recuento,ymax=max(recuento)*1.05, fill =
cO)) +
geom_bar(stat = 'identity', position = 'stack', col="black") +
facet_grid(~ variables)+
geom_text(aes(label = recuento), size = 5, hjust = 0.5, vjust = 1,
position ="stack")
