border colour for geom_dotplot

[Wesley Goi]

Hi, 

Is there a way to set the border color of individual dots in geom_dotplot by Winston Chang?

https://github.com/wch/ggplot2/wiki/geom_dotplot. 

Actually i would like to remove them.

You can do something like this:

  geom_dotplot(colour=NA)

Thanks so much, that did the trick

Sorry to bother again but staying "in topic" regarding each dot, 

could other shapes be encoded into geom_dotplot? ie. maybe triangles?
