I don't think that you can do this with points (though I would be happy to be proven wrong), but you could look at the my.symbols function in the TeachingDemos package. You need to create a function to plot the symbol that you want with the rotation that you want, but then you can use it to place the symbols/points on the plot with the desired rotation, see also the ms.polygram and ms.polygon functions for examples that include a possible rotation (adj argument).

I'm trying to place points around a radial diagram such that the y-axis of individual shapes are oriented with the radii of the circle rather than the y-axis of the larger plot area. Perhaps something analogous to the 'srt' and 'crt' functions for text that appear under 'par'?
