R help - Feb 2011 - Frequency plot --- stacked symbols

Hi,

We were wondering how we could make a stacked frequency diagram such as this
one:

http://msemac.redwoods.edu/~darnold/math15/liz.pdf

We don't necessarily need the shaded "balls", other characters
would be fine, such as stacks of x's.

See the ?dots? function in the ?TeachingDemos? package or the ?dotPlot? (not 
to be confused with ?dotplot?) function in the ?BHH2? package. Note that 
both packages define a ?dots? function, and one of them with mask the other 
if you load both packages.

You might also be interested in the ?stem? function (part of the default R 
packages).

Hi David,
you can use base 'stripchart'

stripchart(rbinom(100,size=10,p=.3),method="stack",pch=21,at=0,bg="lightblue",col="blue",offset=.5,cex=1.5,xlim=c(0,10))

and set 'pch' as you wish, e.g. as in

example(points)
