How to draw scruffy diagrams in R?

Any ideas how to do "scruff开发者_JAVA技巧y" bar and scatter plots (like yuml) in R?

If you have in mind the exact replicate of the sample graph on the link that you have provided... well, let's say that you have very slim chances of success...

But I recall an article in The R Journal Vol. 1/1, May 2009, written by THE Paul Murrell - Drawing Diagrams with R. Murrell suggests two packages: shape and diagram.

I haven't done any diagram in R so far - I prefer Dia application available on Linux platforms (and there are ports for MacOS and Windows). Murrell's article is concentrated on low-level graphing capabilities, so it's very flexible, but on the other hand a bit labour-intensive... I'm sure that learning effort pays off in the end, but I usually need something quick, so I use Dia.
