I'm not familiar with the plots you mention, but the following is a
quick attempt to create the plot you describe.
data<-data.frame(
org=1:10,
q1=sample(1:10,replace=T),
q2=sample(1:10,replace=T),
q3=sample(1:10,replace=T))
# This generates a random data set like the one you describe. It
looks like this:
# org q1 q2 q3
#1 1 9 1 4
#2 2 1 2 1
#3 3 1 3 7
#4 4 10 9 6
# ...
n<-ncol(data)-1 # NUMBER OF ORGANIZATIONS
new.mat<-apply(data[,-1],2,function(x){xtabs(~factor(x,levels=1:10))})
plot(rep(1:n,each=10),rep(1:10,n),
pch=16,
cex=c(new.mat),
xaxt="n",
xlab="Question",
ylab="Score")
axis(1,at=1:n)
Instead of cex=c(new.mat), you can supply a function of new.mat, say
cex=f(new.mat) to specify the size of the dots.
Hope that helps.

Hi,
Fairly new to R - have done basic plots but now faced with
plotting a matrix/table of results -I know what I want but cannot
find out how to do it.
Basically have individual questions ( x) to which an organization
can rate themselves 1-10 (y) what I want to show is a
matrix/density type plot (like the matrix corrolation plots I have
seen on R graph site) showing for eac question (x) a circle or
shape of varying size and/or colour to represent the number of
organisations rating themselves for each value of y.
Hope this makes sense, any advice would be gratefully received.
