[R] matrix plot

[hairryharry]

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.
