Look at the xpd option in ?par. If you set par(xpd=TRUE) you should be able to add a segment for what you want. But please let me know if someone gives you a better way to do this.

In case the answer depends on exactly what I'm trying to do, see below. I'm using R v. 2.8.1 on Windows XP. Cheers, Alan I'm trying to make a horizontal barplot with a column of numbers on the right side. I'd like to put a line between the column header and the numbers. The following reconstructs the idea - just copy and paste it in: aa <- 1:10 plot.mtx2<-cbind(aa,aa+1) colnames(plot.mtx2)<-c("Male","Female") lci2<- cbind(aa-1,aa) uci2<- cbind(aa+1,aa+2) par(mar=c(5,6,4,5)) cols <- c("grey79","grey41") bplot2<-barplot(t(plot.mtx2),beside=TRUE,xlab="Malaria death rates per 100,000", names.arg=paste("state",aa,sep=""),legend.text=F,las=1,xlim=c(0,13), horiz=T, col=cols, main="Malaria death rates by state and sex") legend(8,6,legend=c("Female","Male"),fill=cols[order(2:1)]) segments(y0=bplot2, y1=bplot2, x0=t(lci2), x1=t(uci2)) mtext(10*(aa+1),side=4,line=4,at=seq(3,3*length(aa),by=3)-0.35,padj=0.5, adj=1,las=1,cex=0.85) mtext(10*aa,side=4,line=4,at=seq(2,3*length(aa)-1,by=3)-0.65,padj=0.5,ad j=1,las=1,cex=0.85) mtext("Estimated",side=4,line=3,at=3*length(aa)+2.75,padj=0.5,adj=0.5,la s=1,cex=0.85) mtext("Deaths",side=4,line=3,at=3*length(aa)+1.25,padj=0.5,adj=0.5,las=1 ,cex=0.85) ______________________________________________ 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. =================================== P Please consider the environment before printing this e-mail Cleveland Clinic is ranked one of the top hospitals in America by U.S. News & World Report (2008).
