So the speed of the rendering of the images in personograph may indicate that it is best to just
made adaptations to this line of work.
The icons in this package are in the inst folder.
They are named:
1.ps.xml
and represent post script files turned into xml with the grImport package.

Adding extra icons should be quite feasible. Find a postscript file (PS) and use grImport to turn it into xml.
However, is it possible to plot with different icons? I suspect so but I will need to learn more coding to make that certain, I think.
Second issue would seem to be to be able to change the number of rows - the dimensions argument does this...
Again this shouldn't be too difficult, I think...
Finally adding the random element might be a bit more difficult...
So here is some more reading:
