Hi all,
I have a sample of data set,
dat <- read.table(header=TRUE, text='Lab count
A 24
B 19
C 30
D 18')
barplot(dat$count, names.arg=c("A", "B", "C","D"),
col="blue",
ylim = c(0,30),
ylab = "Count",
xlab = "Grade")
I want add the number of counts at the top of each bar plot. How can I do that?
Thank you in advance
