Thank you! This worked beautifully. Can you help me adapt the code to
do the same thing for a plot of means? The application is not a simple

plotMeans(rich.small$ALL, rich.small$sample, error.bars="se")

Hi Sagan,
Let's see, plotMeans is in the Rcmdr package. After installing it, I
couldn't get it to plot, but upon exiting the Rcmdr window I worked out
that the second argument (factor1) must obviously be a factor. After
correcting this:
rich.small<-data.frame(ALL=rnorm(240,5),
sample=factor(c(rep(0,60),rep(2,50),rep(4,40),
rep(7,30),rep(10,30),rep(18,30))))
I get a plot, but I can see no way of adjusting the positions of the
means displayed. I suggest:
plot(c(0,10,13,16,19,94),
by(rich.small$ALL,rich.small$sample,FUN=mean),
xaxt="n",ylim=c(4.7,5.4))
library(plotrix)
dispersion(c(0,10,13,16,19,94),
by(rich.small$ALL,rich.small$sample,FUN=mean),
by(rich.small$ALL,rich.small$sample,FUN=std.error))
staxlab(1,at=c(0,10,13,16,19,94),labels=c(0,2,4,7,10,18))
Jim
