Here's a toy example set.seed(1) y <- rt(30, 3) boxplot(y) identify(x = rep(1,30), y = y, label = format(y, digits = 2)) ### now click on the outlier in the plot and you should see "-7.398" ### beside the outlier > 2. How can I put two boxplots in one x-y axis? x <- rnorm(10) y <- rnorm(20, 3, 5) z <- runif(30) boxplot(x, y, z, labels = c("x", "y", "z")) ### - or - boxplot(list(x = x, y = y, z = z)) > Thanks. > > Yulei > Stephen Weigand Rochester, Minnesota, USA ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
