I think that one of the packages, perhaps Hmisc or plotrix does this but you can also do it just using text()
Example plot(b~a,data=df, xlim=c(min(df$a)-5,max(df$a)+5), ylim= c(min(df$b)-5,max(df$b)+5)) text( df$a+1,df$b, labels=df$year) Alternatively you can do this in ggplot library(ggplot) p <- ggplot(df, aes(x=a, y=b, label=year)) p + geom_text() --- On Sun, 5/2/10, Ozan Bakis <oba...@gsu-giam.net> wrote: > From: Ozan Bakis <oba...@gsu-giam.net> > Subject: [R] adding year information to a scatter plot > To: r-help@r-project.org > Received: Sunday, May 2, 2010, 3:25 PM > Hi R users, > > I would like to add year information to each point in a > scatter plot.
