Barplots
Hello, Thanks for the suggestion below. I did one of my figures and it worked perfectly. I tried it on my second figure and got double-labelling on the first bar. I used the same code to create both figures, and the same code to label. I've attached the code for one of the plots (there were 3/figure) if anyone has a chance to figure out why. Thanks, Suzanne

Can anyone tell me how to label individual bars on a barplot? I want to put an "*" or letter ABOVE the bar to denote statistical significance. Is this possible and how?
You can use text() to put arbitrary strings in your plot. So you only
need to add some offset to your y-values and work out the x-positions:
y <- c(10,12,15,8)
lab <- c('*','**','***','*')
barplot(y, ylim=c(0,20), space=0.5)
x <- (0:3*0.5)+1:4
text(x, y+1, lab, adj=0.5)
