[R] rotating points on a plot

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).

Hope this helps,

Subject: [R] rotating points on a plot

Anybody know how to rotate shapes generated with the 'points'
function?  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'?

Thanks,
Rich
