nana, If you save the boxplot as an R object, you can access various parameters of the resulting plot. Since we don't have your data, I'll give you an example with the preloaded ToothGrowth dataset:
ToothGrowth<-y b<-boxplot(y$len~y$dose,xaxt="n") Now, if you type b at the R prompt, you will see that b$n contains the number of points you are looking for. So let's say you want to show those numbers on the X axis, you can do: axis(1,at=1:length(b$names),labels=paste(b$names,"\n(n=",b$n,")",sep="")) On Thu, Jun 24, 2010 at 2:47 PM, David Winsemius <dwinsem...@comcast.net>wrote: > > On Jun 24, 2010, at 7:45 AM, nana wrote: > > >> Hi everyone, >> I made this set of boxplots that would show me the widths of some sites >> broken up by some chromosome, but I don't know how to make it indicate the >> number of data points that created the boxplot. >> How do I do that? >> >> boxplot(data$site~data$chr,varwidth='TRUE') >> >> ?boxplot > ... read the Value section > ?text > > > > >> >> -- >> View this message in context: >> http://r.789695.n4.nabble.com/boxplot-width-tp2266805p2266805.html >> Sent from the R help mailing list archive at Nabble.com. >> >> ______________________________________________ >> R-help@r-project.org mailing list >> https://stat.ethz.ch/mailman/listinfo/r-help >> PLEASE do read the posting guide >> http://www.R-project.org/posting-guide.html >> and provide commented, minimal, self-contained, reproducible code. >> > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
