introduction slides for beginners

Hi all,

    does anybody have slides for a 1 to 3 hour crash course into R,
that I would be allowed to recycle to show a few people the light?

I have some stuff I used for 5 x 1 hour presentations at

http://www.stat.wisc.edu/~deepayan/SIBS/slides/

meant to complement the first chapter of 'An Introduction to R'. It was
aimed at undergrad students without any Statistics background (they were
supposed to get some in the rest of the course), so it might not be
appropriate for you.
