Beatriz, In this case, use the car package and run the following:
> bp <- Boxplot(DATA$ave, data= DATA, main= "Average Size", labels=DATA$num, > Id.method=c("y")) This will print out the labels 211 & 225 beside the outlier points. As you can see, the instruction assigns the values in the num column in the DATA data frame to the labels. If you prefer the interactive option, replace id.method=c("y") with id.method=c("identify") Kind regards, José José Iparraguirre Chief Economist Age UK T 020 303 31482 E jose.iparragui...@ageuk.org.uk Twitter @jose.iparraguirre@ageuk Tavis House, 1- 6 Tavistock Square London, WC1H 9NB www.ageuk.org.uk | ageukblog.org.uk | @ageukcampaigns -----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Beatriz González Domínguez Sent: 09 April 2013 17:32 To: r-help-ow...@r-project.org; R Help 1; R Help 2 Subject: [R] Boxplot Labels OK Dear all, I have just sent an enquiry but probably I hadn’t expressed myself properly. Could anyone help me with the following? When I run the code on my data I get a boxplot with outliers identified by numbers 200 & 201. However, what I would like is to label these outliers with their corresponding “DATA$numâ€? values of the data frame. In this example, the outliers should be labelled as: 211 & 225 Do you have any idea of how I could do this? Please, if you need any more details just get in touch. Many thanks in advance! ## R CODE #DATA num <- as.numeric(200:225) ave <- c(0.5, 1, 1.6, 2, 2, 2.3, 2.5, 2.4, 3, 3.2, 3.3, 7.2, 4, 4.8, 3.5, 2.7, 3.1, 2.8, 4.1, 2.0, 2.5, 2.1, 3.4, 2.5, 2.6, 7) DATA <- data.frame(cbind(num, ave)) rm(num, ave) #BOXPLOT x11() bp <- boxplot(DATA$ave, data= DATA, main= "Average Size") identify(x= bp$group, y= bp$out, labels= DATA$num, cex = 0.7) Bea [[alternative HTML version deleted]] Please donate to the Syria Crisis Appeal by text or online: To donate £5 by mobile, text SYRIA to 70800.
