Hi Mary, One can use arrows too...
Here is the code : x<-seq(75,225,0.1) plot(x,dnorm(x,mean=140, sd=15), type='l', col='navy') *arrows(149,0,149,dnorm(149,140,15),length=0) *par(new=T) plot(x,dnorm(x,mean=150, sd=15), type='l', col='orange',axes=F) Regards Radha On Sun, Jul 26, 2009 at 5:09 AM, Mary A.
