[R] Problems with savePlot() and postscript under Snow Leopard

[Michael Denslow]

Hi Hannes,

>> species.n <- as.numeric(Species)
>> plot(iris, col = species.n)
>> savePlot(filename="IrisTestPlot", type="png")

You might try

quartz.save("Iris.png","png")

I think this is an undocumented function that is specific to the Mac GUI.
You can search the r-sig-mac archives for some discussion/information.

Hope this helps,

Michael
