R help - Dec 2006 - specify point shape for ggplot (equivalent to pch)?

Hi

is it possible to specify the shape of the point to be used in ggplot 
(as with pch in plot)? I couldn't find anything in the help.

Thanks

Rainer

I was looking for that the other day while just poking
around with ggplot and did not see it but I a very new
to R and to ggplot. 

However have a look at the function map_shape.  It
looks to me like this decides what points are used but
this is just a guess.

See the last example in ?qplot
