Dear all,
since my problem could not be solved in the general R mailing list,
I'll post the issue again in this specific mailing list.
I tried:
iris
species.n <- as.numeric(Species)
It would help if yuo access the column properly. "Species" is only
meaningful within "iris".
plot(iris, col = species.n)
savePlot(filename="IrisTestPlot", type="png")
If you want a png plot then open the png() device and close it when
you are done:
species.n <- as.numeric(iris$Species)
png("test.png")
plot(iris, col = species.n)
dev.off()
Produces the requested plot in the working directory and Preview
opens it without problem.
I also got a slightly different sort of success with:
plot(iris, col = species.n)
quartz.save("test2.png", type="png")
The background was completely transparent. I can see useful
application of that feature in creating "after-the-fact" overlays of
other plots. Reviewing the help page for ?quartz, it appears this is
the expected result. Plotting with the png() device created a white
background (as would be expected after reading its help page.)

and got the error message:
Fehler in savePlot(filename = "IrisTestPlot", type = "png") :
kann nur aus 'X11(type="*cairo")' Devices kopieren
(sorry, I have a german version of R).
I tried:
postscript("IrisTestPlot.eps",
paper="special",height=6,width=6,onefile=FALSE,horizontal=FALSE)
and
postscript(file="IrisTestPlot2.pdf", onefile = FALSE, horizontal =
FALSE, paper = "special", width = 8, height = 8)
in both cases there are files produced that cannot be opened. Error
message: the bounding box is missing.
According to Michael's advice I tried:
quartz.save("IrisTestPlotquartz.png","png")
and got:
postscript
5
but no file.
as well as:
system('open IrisTestPlotquartz.png')
It states that the files does not exist.
And I tried:
plot(iris)
dev.cur()
And got the answer:
postscript
3
and again no file.
I use 64 bit R under Snow Leopard.

What could be the problem and how can I solve it?
Thank you very much in advance for your time and advices!
