Hi: I need help with geom_text(). I would like to count the number of Locations and put the sum of it right above each bar. x <- "Location Lake_dens Fish Pred Lake1 1.132 1 0.115 Lake1 0.627 1 0.148 Lake1 1.324 1 0.104 Lake1 1.265 1 0.107 Lake2 1.074 0 0.096 Lake2 0.851 0 0.108 Lake2 1.098 0 0.095 Lake2 0.418 0 0.135 Lake2 1.256 1 0.088 Lake2 0.554 1 0.126 Lake2 1.247 1 0.088 Lake2 0.794 1 0.112 Lake2 0.181 0 0.152 Lake3 1.694 0 0.001 Lake3 1.018 0 0.001 Lake3 2.88 0 0" DF <- read.table(textConnection(x), header = TRUE) p <- ggplot(DF,aes(x=Location)) + geom_bar() p + geom_text(aes(y=Location),label=sum(count)) # Error because count doesn't exist in dataset What should I use instead of 'count' to be able to sum the number of Locations?
How about ... ?
p + geom_text(aes(label=..count..), stat="bin",
vjust=1, colour="white")
