You can also eliminate the outliers from boxplots with the "outline=F" parameter.

If you draw the whiskers out to the extrema of the data you may wish to omit the "outliers", which are encoded by the out and group components of boxplot's return value: d <- split(Nile, factor(time(Nile)>1902, labels=c("pre-dam", "post-dam"))) par(mfrow=c(1,2)) b <- boxplot(d, main="Default Boxplot") b$stats <- sapply(d, function(x){x<-x[!is.na(x)];s<-sd(x);m<-mean(x);c(min(x),m-s,m,m+s,max(x))}) b$group <- b$out <- numeric(0) # no outliers when whiskers go to min and max bxp(b, main="Non-robust Boxplot") Bill Dunlap Spotfire, TIBCO Software wdunlap tibco.com > -----Original Message----- > From: r-help-boun...@r-project.org > [mailto:r-help-boun...@r-project.org] On Behalf Of Gabor Grothendieck > Sent: Monday, September 26, 2011 7:36 AM > To: p...@pricom.com.au > Cc: r-h...@stat.math.ethz.ch > Subject: Re: [R] Boxplot BUT with Mean, SD, Max & Min ? > > On Mon, Sep 26, 2011 at 9:56 AM, Philip Rhoades <p...@pricom.com.au> wrote: > > People, > > > > It appears that there is no way of getting Boxplots to plot using > > Mean, SD, Max & Min - is there something else that would do what I > > want?
